Completely locked out of playing one character

This is happening only for one of my characters. Two other seem unaffected.

After my huntress reached the first map of act 3 it started crashing out to desktop every few seconds. After 2-3 crashes it wouldn't even get to load the environment, is just crashing right after loading screen.

I took a break for 12h or so and i was able to log for 3 seconds, trhow a screen - crash to desktop. Now is again crashing right after load screen.

I aam able to log and play just fine with my other two characters.

I have the same problem and can't find an answer
