Strange Crash, Please Help!

Hi, for the last month or so when playing on desktop my Hearthstone always crashes my computer after 10 - 30 minutes of playing. The screen freezes and a low tone plays through my speakers until I manually shut it off.

This only happens with Hearthstone, I play more hardware intensive games just fine (Valorant, GTA, etc.).

I have reinstalled the game, deleted Hearthstone %appdata folder, reset in-game defaults; no fix. My windows is fully updated and my drivers are up to date (as far as I know). I’ll include below my pc specs. Is there anything else I can do to troubleshoot this issue?
Please help, thanks!

cpu: i7 - 9700
ram: 16 gb ram (same speed)
gpu: ryzen RTX 5700
1tb solid state drive
500w power supply
(i just replaced all of my fans so cooling shouldn’t be an issue)
