An unexpected error that could come up while playing a Call of Duty game (or even launching it) is the UI error. If you have faced one or more of the COD UI error codes like 85118, 27711, 54909, 45867, 88433, 17109, 26465, 43399, 85870 etc, here’s what you can do to potentially fix the problem.
How to Fix Call Of Duty (COD) UI Error?
Close the Game and Restart it
If it’s a bug that has randomly reared its head, close the game and launch it again. While a fresh restart should ideally fix it, if the error comes up again and many players are talking about it on social media, check out the point mentioned below.
Check for Updates
In case the developers have released a hotfix which solves this problem, the first thing you should do is update the game to the latest version. Social media will come in handy to check whether it is a widespread issue or if it’s only happening to you. But if the devs have posted about still investigating the problem, then all you can do is wait until the fix is rolled out.
Close Background Programs and Restart your System
Some apps and programs running in the background on PC could interfere with a game and could also hog up the resources intended for it. To ensure a smooth performance without interruptions, close all the unnecessary applications including antivirus software, VPN etc. Then, restart your PC and check whether you are getting the COD UI error again. The same goes for console players – turn off the system, restart and try to launch the game again.
PC players can Verify Steam Game Files
If the problem is occurring due to wrongly installed files or if a file is corrupt, verification of game file integrity can fix these issues.
- Start Steam.
- Find the game in your library.
- Right-click on the game and click on Properties.
- Find the Local Files tab.
- Click on Verify Integrity of Game Files.
- After the process is done, reload the game.
