Game Client Hard Freezes after 1-2 minutes

Okay, after testing on my end, I can confirm this is actually the solution, at least for this problem, thank you Shopmill for going the extra mile to figure it out properly. Now that I recall, I remember modding Rimworld heavily in the past and messing with that specific setting. It looks like you need to disable "Randomize memory allocations (Bottom-up ASLR)" for Battlefield 6 to make your game not crash, probably due to Javelin Anti-Cheat shenanigans. DO NOT UNDER ANY CIRCUMSTANCES ATTEMPT TO DISABLE THIS SETTING GLOBALLY, THIS COULD BE DANGEROUS. ONLY EXEMPT THE BATTLEFIELD 6 EXE AS SHOWN HERE

For your information, Battlefield 6 Open Beta is in a folder called "Glacier Events" on Steam, and the exe is named bf6event.exe.

If you're still crashing after this, I'm so sorry I couldn't help you fix it alongside me, but this at least seems to cover crashes specifically where the game boots up properly but then crashes either immediately or after a minute (probably when the anti-cheat tries to check through your memory and Windows blocks it)

Marking this as solution for the time being, feel free to make another thread if you still crash after this
