Uninstall produced "The website encountered an unexpected error."

When trying to uninstall Rules (drupal 9), my site did this. I've tried everything to get it back but it will not come back on. Any suggestions before I do a restore. Thanks

The website encountered an unexpected error. Please try again later.
