Unable to start PsyhoPy3 2020.2.4/.10

I already built two experiments in PsychoPy. Now I wanted to use a mirophone response, but that didn’t work, so I reinstall PsychoPy three times.
Then I changed the auditory library (file → preferences → hardware → auditory library) only to ‘pyo’. After that nothing works anymore.
When I click to open PsychoPy or the Builder, it loads for some seconds but nothing happens.
When I open one of my experiments, the python sreen opens for 1 second and then it close itself. I was able to take a screenshot (I uploaded it).
Now I don’t know what to do.
Are there any ideas?

Looks like some extra curly braces are around the ‘sounddevice’ preference.

When you uninstall psychopy, can you also check that the
C:\Users\[USER_NAME]\AppData\Roaming\psychopy3 folder is deleted, before reinstalling? Replace [USER_NAME] with your windows user name.

Now it works, thank you very much!
