I've been running into TPM errors while using Windows 11, and I'm starting to think I've figured out what's going on. It seems like Valorant's anti-cheat system, Vanguard, is the culprit. Every time I launch Arc Raiders after starting Valorant, my PC freezes and restarts. It looks like Arc Raiders tries to access the TPM or some secure system functions, but Vanguard messes things up, blocking the TPM session and leading to crashes. Has anyone else had this experience?

Be careful when tweaking your BIOS settings or disk configurations; you might run the risk of losing data. Always back up your important files before making any changes!
Definitely check if you have the latest BIOS updates. I remember there were some TPM issues linked to certain games last summer, and updates were rolled out to address those.
It’s funny how everyone in the tech community warned against kernel-level anti-cheat systems, and here we are. Riot, looks like you’ve got a lot of folks concerned now!

Thanks for the tip! I just checked, and my motherboard is up to date.
