The game seems to be stable on low level gameplay, but I experience a lot of game crashes on higher levels in Primal Park, AOV. I had also crashes in Meet Factory, Dipluce Horizon, District 6, Innocent Daydream and Golden Citadel (solo and with a team). Sometimes I can play an hour or even more, sometimes the crashes happens after a few minutes of gameplay. Sometimes the game is freezed forever instead of crash, so I need to kill the entire process tree manually. Changing some game settings, computer (with AMD GPU), Proton versions, using OpenGL instead of Vulkan doesn't help.

Alt-tab (changing the window focus) or changing the game settings in 5 cities (Rucco Town, Candus City, Grace City, Ruin Fortress, Dipluce Horizon) takes about 5 seconds and the game is freezed in meantime. No issues in districts, Grasscover Camp, Gate to Golden Citadel.
