Unable to Edit "Text Formats and Editors" in Drupal 10 with Markdown 3 and CommonMark 1

Problem/Motivation

I am experiencing an issue with Drupal 10 where I cannot edit the Text Formats and Editors settings. When I click Configure, the system displays a blank page.

My current setup:

Drupal 10
Markdown 3
CommonMark 1

However, when I downgraded to Drupal 9.5.11, I was able to edit Text Formats and Editors without any issues.

Has anyone encountered this issue before? Could this be related to the Markdown module or CommonMark library in Drupal 10? Any suggestions for troubleshooting or resolving this issue would be greatly appreciated.

I experience this issue too. But with error reporting on, I get the following error:

Fatal error: Class Drupal\markdown\BcSupport\SubformState contains 2 abstract methods and must therefore be declared abstract or implement the remaining methods (Drupal\Core\Form\FormStateInterface::setIgnoreDestination, Drupal\Core\Form\FormStateInterface::getIgnoreDestination) in /web/modules/contrib/markdown/src/BcSupport/SubformState.php on line 16

For that error, there already is an other issue: 🐛 Subformstate incorrect interface error Active
So assume that this issue is a duplicate of that one.

Feel free to reopen this issue if the reason that you saw a blank page was caused by a different error. (Check the logs on /admin/reports/dblog after you faced the blank page or enable error reporting on /admin/config/development/logging.)
