After updating to Drupal 11.4.1, I get a white screen with the message: "The website has encountered an unexpected error. Please try again later."
I cannot work in the administration area; only a white screen appears.
The website is visible online at http://www.sparrowhouse.nl  I can view the site even when logged in, but I cannot access the admin area; that is when the white screen appears.
I host my website using Plesk.

One reason this happens is if you forget to run your DB updates after upgrading.
