Game : Space Hulk: Tactics
Ongoing issue on steam since 2018. Many many reported similar issues all over the internet the last two years but no solution.
When trying to run in windows 10 or windows 11 the game loads up supporting studios short video runs but when the game gets to the loading screen it drops out back to desktop with no error message and also crashes steam app. Each time you have to restart app and log in again..

Trying to run it on Linux: Manjaro, Pop OS!, Fedora or Garuda in all cases when hitting start in steam doesn't load anything just crashes steam app immediately. Tried with Proton Layuer 6.3-8 , 7.0-1 and experimental .... does the same thing with all of them.

Digging into the game files to look for some crash report all I could find is this:
[CrashReportClient]
bHideLogFilesOption=false
bIsAllowedToCloseWithoutSending=true
CrashConfigPurgeDays=2

Some people claim it's something to do with Unreal Engine 4 combined with 11th Gen Tiger Lake CPU that may cause the crash but no definite Answer. My friend have an all AMD Machine and it works for him no problem (2nd gen thread ripper and Vage 64 GPU)
