I ran into this problem too using IMCE Version: 3.0.9 with core CKEditor 5 and Drupal Version: 10.1.5.
There is a workaround if you still want to use the "Limit allowed HTML tags and correct faulty HTML" filter.
By default, CKEditor 5 uses these tags .
IMCE uses . So "data-caption" and "data-align" are missing.
You cannot manually edit the allowed HTML tags with CKEditor 5 (Filter settings tab - Limit allowed HTML tags and correct faulty HTML ). But you can add then to the Manually editable HTML tags under the Source editing tab. Just add "" to it.
Seems to work.
I also got this error but in Drupal Version 10.1.5. but without editorkit.
Using /8.x-2.x-dev solved it.

Hi Khairul,
Did you find a solution for this? We are looking for something similar.
Thanks,

My issue might not have been the same as your's because I only got the WSOD when I edited pages and articles.
The error messages were not helpful so I added this line to settings.php (in a local copy).
$config['system.logging']['error_level']='verbose';
It gave sufficient detail to work out what was going wrong. From there I could see a contributed module was messing things up.
Good luck,
Keith
I have the same error in local and production copies of my site. I'm still not sure what it causing it.
I tried different themes, but still get the same error.
