How do I rectify error with AVD GPU issue ( invalid GPU mode angle9 )?

I cannot seem to rectify by reinstalling the emulator or even reinstalling android studio .

I have tried to click on menu for the Virtual device but the screen shows an error message.

I had the same problem and finally solved it by starting the emulator from commmand prompt with with option -gpu host:

emulator -avd Pixel_3a_API_29 -gpu host

If you don't remember the name of the avd, you can list them with:

> emulator -list-avd
Pixel_3a_API_29

If you don't have the emulator.exe on path, you can add it with:

set PATH=%ANDROID_HOME%\tools;%PATH%
