The game may have a 60 hertz monitor requirement. Removing 60 hertz registry with CRU software may have caused the problem. Try the game with a different TV connection for finding the cause of the problem. If the problem still exists, try re-installing VCRedists.
The game runs fine at 144hz using 20.5.1 driver, The game just closes itself down when trying to load the initial title screen, The only other time it does this is when there is no connection to steam, so i am thinking it could be a conflict between the driver and the network coding in the game?
OP and you seem to have different problems. If the game has 144 hertz support, it is best to look for the problem in the game (data control required), required softwares (vcredists and dx installation) or system settings (location etc...). Game DRM may not even run if the game does not see the user system location. Your problem seems different.
