Abrupt crash after performance hit

I’ve noticed recently that the game seems to crash abruptly during matches. I’m not sure what’s been causing it, but for me it happens after getting sudden performance drops previous match.

Today I was playing a Fiesta match and midway to the end of the match my performance took a massive noise dive (dropped from 60fps to 20fps) costing me the game. Next match and 30 seconds in the match my game abruptly crashes straight to desktop in a millisecond.

This is the forth time this has happened to me this month and I have tried multiple fixes (driver updates, graphics adjustments and reinstalls). Not sure if others have the same experience as me and even though I order a new gpu recently, I’m worried this issue might persist.
