Game Crashing when trying to load things

Hello all,

I'm not as experienced with the game nor know much of the Necro league. I play on Steam.

I've been levelling a Dualist in the early stages of Act 1 and was doing fine until today, it all started when I went to click the add stash tab icon in the stash menu. The game crashed and closed.
I went to play normally was in the instanced area with undertaker, but soon as I left the game froze for 2 frames and crashed.

I played the game again and tried this again, all seemed fine. I accidentally pressed the 'M' key, seen the loading icons and the game crashed.

I never encountered these issues before and I'm quite concerned this will affect my experience when Kalguur launches.

Has anyone experienced this of late, is there any solutions?

Thank you.
