api - Why the android studio emulator wont work?

Question

Since yesterday the android studio device emulator wont work any more.

Didnt change anything of the project and before everything worked very well. Tried to change the compile and target version the build versions and also some different api but it wont work. I deinstalled android studio and also deinstall and install all sdk tools but nothing worked so far. Tried to change the adv settings and also looked up in the internet but didnt find a solution. There isnt any errors or something that looks suspicious in the logs and dont know how to solve it and run it.

The display stay white when i start the application only the status bar is colored with the color i chosed.

Run:

Connected to process 6174 on device 'Pixel_4_XL_API_30 [emulator-5554]'.
