I had the same issue in drupal core 10.2.4. I tried #7 and it saved my day. Thanks a lot.
I also faced the same issue in drupal 9.
I got the solution - In this page "/admin/config/media/image-toolkit", select the radio button "ImageMagick image toolkit" and remove the path already exist in the field "Path to the package executables". Again select the radio button "GD2 image manipulation toolkit" and save configuration.
I am facing this issue in drupal 9.5.9.
Any solution for this?
I am also having this same issue. I have tried the patch in #6, but no use.
Is there any other solution?
I also have the same error. Any solution?
I also got the same error.
Symfony\Component\Routing\Exception\RouteNotFoundException: Route "entity.contact_form.entity_permissions_form" does not exist. in Drupal\Core\Routing\RouteProvider->getRouteByName() (line 206 of /var/www/html/ADB-AP3F/core/lib/Drupal/Core/Routing/RouteProvider.php).
I was using the contact storage module version 8.x-1.1. And I upgraded it to the version 8.x-1.3. Now the error disappeared and I can edit the contact us form.
