Blocks can't get excluded from being displayed on selected pages

I can't reproduce this bug as written so please determine the additional steps to reproduce it.

I'm not sure what else would I need to do, maybe it's happening because I'm using the Tara Drupal theme?

That's something you could test on your end.

Ho would i test it precisely?

Start a fresh installation of Drupal and try to reproduce it there. If you can't, try adding themes or modules that you are using until you find which one causes the problem.

If this problem was discovered on a version of Drupal that is not 11.x, add that information in the issue summary and leave the version at 11.x. In Drupal core changes are made on on 11.x (our main development branch) first, and are then back ported as needed according to the Core change policies → . Also mentioned on the version → section of the list of issue fields documentation.
