This can be reproduced by running, for example, yowasp-yosys --version:

C:\Users\Maya>yowasp-yosys --version
Yosys 0.23 (git sha1 UNKNOWN, ccache clang 11.0.0-2~ubuntu20.04.1 -Os -flto -flto)
Traceback (most recent call last):
  File "C:\Users\Maya\AppData\Local\Programs\Python\Python311\Lib\shutil.py", line 624, in _rmtree_unsafe
    os.rmdir(path)
PermissionError: [WinError 32] The process cannot access the file because it is being used by another process: 'C:\\Users\\Maya\\AppData\\Local\\Temp\\tmpt5ul_igjyosys'

During handling of the above exception, another exception occurred:

    _os.unlink(path)
PermissionError: [WinError 5] Access is denied: 'C:\\Users\\Maya\\AppData\\Local\\Temp\\tmpt5ul_igjyosys'

During handling of the above exception, another exception occurred:

(the exception chain continues indefinitely until the recursion limit is reached)
