I have updated my website from D9 to D11 version. After this update everything is working fine except one issue. And the problem is that when i am trying to add any new field to any of my content type the i am not able to do so. Getting this error: TypeError: Cannot access offset of type Drupal\Core\StringTranslation\TranslatableMarkup in isset or empty in Drupal\Core\Plugin\DefaultPluginManager->doGetDefinition() (line 45 of core\lib\Drupal\Component\Plugin\Discovery\DiscoveryTrait.php).
Switching to CKEditor 5 does not work. It seems some required javascript libraries are not included in CKEditor 5. These Javascript libraries are 404 after the switch:
drupalEmphasis
drupalHtmlEngine
drupalImage
linkit
I am unsure where these libraries are supposed to be loaded from, though.
I have a site based on Drupal 7 and now want to move it to 10. I used the migrate module and got the data moved over and installed the updated version of the same theme and it's a total disaster. The menu isn't working right and I'm getting errors all over the place. The data in the nodes and the users seem fine. At this point I think it's time to try a different approach.
