[2020] GW2 throws me to Desktop when changing Maps

Greetings,

i recently upgraded my System and now i encounter a wierd bug. Everytime i change Map (no Matter if WP or changing Gamemode). GW2 throws me to my Desktop and freezes for a little while.

Systeminfo:

• Intel i5-8400 (6 x 3GHz)
• nVidia GeForce GTX 1050 Ti
• 16 GB DDR4-2400 RAM
• GW2 is installed on an SSD (same SSD as the OS)
• Windows 10 Pro (x64)

Graphicsettings:

All Max with V-Sync disabled (runs at ~62FPS)

I tried to fiddle with the Settings but with no results.

Anyone has any Idea?
