Hi, you should try changing your CSGO Client Version in steam.inf to:
ClientVersion=2000476
ServerVersion=2000476
in
C:\Program Files (x86)\Steam\steamapps\common\Counter-Strike Global Offensive\csgo\steam.inf (make sure to use the csgo not the cs2 one, you can check this by checking for: VersionDate=Oct 12 2023, in the same file).
This technically also applies to the standalone version, there is many working version numbers, this one just happens to work for me
