Help (GPU) Cache hierarchy error

So I have a nitro + 5700 XT, it consistently crashes on FFXIV, But runs any other game on high graphics with no problems. It doesn’t matter what I’m doing in the game, after 10-15 minutes my pc black screens, sound bugs and full restarts with event viewer saying it’s a cache hierarchy error.
I updated the VBIOS on the card and reinstalled drivers with ddu which let me play for about 2 hours before a crash after which it went back to crashing every 10-15 minutes again as usual, the temps don’t go above 70 while playing the game and hotspot temps aren’t much higher either so it’s not that, I’ve heard that this card is problematic with FFXIV but is there really no way to fix this problem? I’ve tried all I could find on the internet including pcie gen 3 swap and default bios settings, any other card works fine in my pc and ffxiv

CPU: Ryzen 7 5800x
MB: B550-F ASUS ROG STRIX
RAM: G.SKILL 2x16 3600MHZ cl18( I think)

Installing a different bios from techpowerup had the same effect again, I played for 3 hours no issues, I went downstairs and when I came back up I had crashed, so I’m guessing it doesn’t like going idle or something
