i have a problem running flask. It started fine until I loaded a simple login form.

when running flask via gitbash, I get an error like this

```
flask run
 * Environment: production
   WARNING: This is a development server. Do not use it in a production deployment.
   Use a production WSGI server instead.
 * Debug mode: off
Usage: flask run [OPTIONS]
Try 'flask run --help' for help.

Error: While importing 'app', an ImportError was raised:

  File "C:\Users\****\AppData\Local\Programs\Python\Python39\lib\crypt.py", line 6, in <module>
    import _crypt

During handling of the above exception, another exception occurred:
