Stages use each issue's current status; the record does not keep status history. 3 closed issues have no dated fix, so their last update date is used.
Unpatched, reported as unpatched, or only partially patched.

- Updated DMZ disconnects wiped players' lootBugAllEarly access (DMZ)ConfirmedReported as unpatchedDMZ servers crash and disconnect players mid-match, and everything they looted in that match is lost; they keep the equipment they deployed with and their progression. Call of Duty said on October 21 that it was resolved, but the launch patch notes do not list a fix, and players on Steam and X kept reporting disconnects and lost loot afterwards.Estimated impact 9.0
- Updated Game does not start from SteamBugPCLaunch (Oct 2026)UnconfirmedUnpatchedSteam players say pressing Play does nothing or the game closes before the first screen, with no error shown, even after verifying files and running as administrator. No acknowledgement found.Estimated impact 8.5
- Updated Secure Boot and TPM checks fail on some PCsBugPCBeta, early accessConfirmedUnpatchedSome PCs that should meet the TPM 2.0 and Secure Boot requirement still fail the game's attestation check, so those players cannot play. Call of Duty says AMD TPM firmware in the 3.x.0.x range is the most common cause and Lenovo machines fail more often. It has updated its attestation wizard and is working with Microsoft and manufacturers on the remaining cases.Estimated impact 8.0
- Updated Campaign and DMZ won't launch on Xbox PCBugPCEarly access (Campaign)ConfirmedUnpatchedOn the Xbox app for PC, Campaign Early Access shows as not installed and will not start, while the same account plays fine on console. A server-side fix on October 16 only helped some players and a second went live on October 19, yet players were still reporting it the next day. Activision Support's known-issues page, re-dated October 22, still lists it as under investigation and says DMZ can be blocked too; its tips are to install Content Pack 1 and check the Microsoft Store 10-device limit.Estimated impact 8.0
- Updated Exfil helicopter refuses to take off and the squad loses everythingBugNot statedEarly access (DMZ)UnconfirmedReported as unpatchedAt extraction, the exfil helicopter sometimes never takes off. The squad cannot extract and loses everything it was carrying.Estimated impact 8.0
- Updated Xbox says pre-ordered players no longer own the gameBugXbox, Xbox PCEarly access (DMZ)UnconfirmedReported as unpatchedSome players who pre-ordered (including Vault Edition) and already played the Campaign and DMZ early access are suddenly told they do not own the game, or are asked to pre-order or buy again. One player says it happened in the middle of a DMZ match. Affected players are locked out until their licence is restored.Estimated impact 8.0
- Updated Washed-out and purple-tinted graphics after NVIDIA driver 621.01BugPC (NVIDIA)Early access (DMZ), NVIDIA driver 621.01ConfirmedUnpatchedSince NVIDIA's 621.01 driver, some PC players see washed-out, pixelated, posterized or purple and green-tinted lighting and shadows in DMZ and Multiplayer, while Campaign can look normal. On October 26 Infinity Ward's Trello board listed the 621.01 visual issues as under investigation and said it is working with NVIDIA to correct them. Two workarounds: a clean installation of an earlier NVIDIA driver (players name 617.42, 617.14 and 616.56), which Call of Duty staff called a temporary workaround for most players; and, unconfirmed, deleting the shadercache folders inside the game's cod26 and sp26 folders and letting shaders rebuild, which several players on X said fixed it. Players report that turning HDR off, a clean reinstall of 621.01, and reloading or restarting shader preloading did not help.Estimated impact 7.7
- Updated Endless "checking for updates" loop at launchBugXbox, PS5Beta, early accessConfirmedPartially patchedOn Xbox and PlayStation the game can keep checking for updates, or asking to exit for an update, without ever starting; some players get an error or crash to the dashboard. In the Beta on Xbox it came from missing content packs, and the installer was changed to prompt for them. In Early Access players on Xbox and PS5 report the loop again, including when launching DMZ. On PC, launching can stop on repeated "Update Requires Restart" prompts; Infinity Ward's Trello board said connection timeouts caused them, and on October 25 moved that card to Resolved (Fix Released); no patch notes list that fix.Estimated impact 7.5

- Updated DMZ keeps crashing on consoles before a match can finishBugXbox, PS5Early access (DMZ)UnconfirmedReported as unpatchedSome console players say DMZ crashes or freezes every match, sometimes before they can finish a single run, even after reinstalling. When it happens mid-run they can lose the gear they took in.Estimated impact 7.0
- Updated DMZ deploys players without the gear they equippedBugNot statedEarly access (DMZ)UnconfirmedReported as unpatchedPlayers who set up a full kit (bigger backpack, armour carrier, weapons) sometimes load into the DMZ match with none of it. This is separate from the known Free Loadout bug because it involves players' own gear. They start the run unarmed and at a big disadvantage.Estimated impact 7.0
- Updated Campaign crashes and hard-locks consolesBugPS5, XboxEarly access (Campaign)UnconfirmedUnpatchedOn PS5 and Xbox the campaign can crash, freeze or hard-lock the console, often during cutscenes and sometimes right when starting the campaign, while other games run fine.

- Updated Kicked for inactivity while spectating in MultiplayerBugAllLaunch (October 23)ConfirmedPartially patchedPlayers who die in round-based modes, mostly Search and Destroy, can be kicked for inactivity while spectating their team for the rest of the round. The October 25 update's patch notes say AFK kicks while spectating in some Multiplayer modes were addressed, and Infinity Ward's Trello card is now Resolved (Fix Released). Players were still reporting inactivity kicks while dead in Search and Destroy on October 26, after the fix.Estimated impact 6.0
- Updated Can't save Loadouts in MultiplayerBugAllLaunch (October 22)ConfirmedUnpatchedSome players cannot save Loadouts in Multiplayer, so they cannot use their own classes. Activision Support's known-issues page lists it as under investigation on all platforms.Estimated impact 6.0

Some say it started after early access. No acknowledgement from Infinity Ward or Activision found.Estimated impact 5.5
- Updated Campaign crashes to desktop with error 0x00001337 on PCBugPCLaunch (Oct 2026)UnconfirmedUnpatchedOn PC, choosing Campaign from the main menu closes the game to the desktop with error 0x00001337 (ntdll.dll), so the Campaign never starts. Some players hit the same error later in the story. Players say verifying files, rolling back drivers and lowering graphics settings did not help. No acknowledgement from Infinity Ward found.Estimated impact 5.0
