Current thread 0x00008bd8 (most recent call first):

Configuring environment variables, no matter how they are configured, does not work.

Solution:
Tried opening the installation package directly and reinstalling it, and making changes in System Applications and Features, but none of them solved it.
I can only find python in settings-applications and features, uninstall it first, and then reinstall it.
The problem is solved, although after re-entering pycharm, the previous library needs to be reinstalled.
