Game wont launch if 64 bit is selected

If the client_log.txt is not getting updated, then this is typically a anti-virus program blocking write access to DST.

@ScottHansen Thanks for your reply.

Let me clarify the issue. I cannot launch the 64-bit version. 32-bit works fine, logs are being generated.
I believe I am having the same issue with this one
Homescreen shortcut not working, 64 bit not launching - Don't Starve Together - Klei Entertainment Forums

Right click steam from system tray > launch down starve together -> will not work because I believe 64 bit is the default
You can only run DST if you open steam>library>play>select 32 bit version

I did turn off the ransomware in the windows settings before posting the issue. I also turned off the Virus Protection and problem still persists.

@ScottHansen I did found the issue.

Today my PC got updated to Windows 11. I just download the NVDIA Experience App and saw that there is a newer version of the Driver. I run the game from Nvidia's Games & Apps tab. DST 64 is now starting. I guess the issue is the OS/Driver update. Thanks for giving the link I realized my GPU driver must be compatible to win 11. Thank you!
