problems on win10 after installing with non admin permissions

after installing python-certifi-win32 as non-admin under windows 10 (python also installed as non-admin) it seems, that every startup of a python runtim environment fails. Even a simple "pip" leads to

PermissionError: [WinError 32] Der Prozess kann nicht auf die Datei zugreifen, da sie von einem anderen Prozess verwendet wird: 'C:\Users\xl09617\AppData\Local\Temp\tmpb257q79d'

translates to: PermissionError: [WinError 32] The process cannot access the file because it is being used by another process: 'C:\Users\xl09617\AppData\Local\Temp\tmpb257q79d' )

If I install it as admin, everything works fine. Is there a solution for that? Or even a explanation?

The full command with trace was (xl09617 is the user id):
