BF6 Beta PC Client Not Launching - Silent Crash After Startup

alright this worked for me.

You need to disable Force randomization for images (Mandatory ASLR) globally or add an exception for bf6event.exe:

• Disable globally (requires PC restart):

– Open Windows Security → App & browser control → Exploit protection settings – Under System settings, turn Force randomization for images (Mandatory ASLR) Off

Restart your PC 

• Add an exception (no reboot needed):

– In Exploit protection settings, go to Program settings → Add program to customize → Choose exact file path – Select bf6event.exe and set Force randomization for images (Mandatory ASLR) Off

Launch the game again.
