the crashes make POE2 unplayeble - PC

hi,
since this week I experienced a lot of crashes in POE2, to the point the game was unplayable, even 2-3 crashes per map.

I play on PC, usually, in co-op with a friend, using a controller.

The things I tried to solve the crashes:

- change the graphics settings to the minimum
- going back to keybord+mouse (I noticed one of the crashes happened when set swapping with controller)
- switch from DirectX to vulkan
- upgrade all the various drivers of my PC and my GPU

Please help I do not know what else I can do.
