The red screen in XCOM: Chimera Squad appears when using the developer console. We’ve talked about it in a separate guide. Below, I will tell you how to get rid of it.
The first way to get rid of the red screen is to completely reinstall the game. If you are playing Steam-version, open your Steam and launch the game through it (the “Play” button). However, the codes will not be available in this case.
The second option is a temporary and repeatable solution. Each time the red screen appears, press the ESC key. It will disappear. That is, in terms of passing it does not present any inconvenience. You’ll just have to press the same key.
