bumping this, i cannot test any of my projects. it’s not a hardware incompatibility thing because i could test a couple days ago on the same computer.

with that said;

x870e aorus stealth v1.0
9950x3d
3080 10GB LHR
32GB ddr5 @ 4800Mhz

Yes. I will send them over once I’m back at the affected computer.

Hi, I don’t see an option to send the file to you via developer forum. Please reach out to me via dm or send me an email at w@wayy.me (if dm isn’t an option for whatever reason?) and I can send you a log file showcasing the issue. Thanks
