PoE2 began to hang and crash very often

Hello!
After the release of patch 0.2.1, the game began to hang and crash very often. Reinstalling the graphics driver did not help. Completely deleting and reinstalling the game didn't help either. After the new patch 0.2.1b nothing has changed except that the loading process of the game has become noticeably longer. The game hangs every map, sometimes even 2-3 times. It's awful! Please help me.

+1 and loosing maps...

Yeah I'm seeing a lot of crashes when transitioning between areas in the campaign. Adjusting CPU core affinity seemed to help for a bit, but it's still not stable.

Looks like something introduced a regression!
