Gutenberg does not load with css and js aggregation enabled

1. Does a clear cache helps to resolve the problem?
2. Does disabling the aggregation helps?
3. Are you able to reproduce the problem on a clean Drupal with Gutenberg installation

I'm asking because we have a couple of sites in production using the combination of versions and aggregated JS+CSS, where Gutenberg just loads normally.

Could it be related to https://www.drupal.org/project/gutenberg/issues/3343392 🐛 Gutenberg is not loading properly Active + the releated Core task?

1. No, clearing cache did not help.
2. Yes, the issue exists only with aggregation enabled as mentioned in the problem description.
3. Have not tried. We have this module installed on a few sites, but have since moved away from using it because of too many issues.

It would be cool, if you could verify it on a clean installation, either locally or via https://simplytest.me just to exclude that it's related to other modules, e.g. advagg, the admin theme, the site being big with a lot of assets.

Don't have time to test right now. I trust that it works if you say it works. The site in question is very basic and uses the Claro admin theme and no advagg. Enclosed is a screenshot of the console errors when Gutenberg whitescreens. What idea what could cause these issues?

It appears to be a similar issue Gutenberg had in Summer 2021. Back then I also had to disable "JavaScript aggregation" in Drupal, to make Gutenberg work again.

Clearing or rebuilding the cache doesn't work.

This applies at least to Gutenberg 2.6 and 2.7 on Drupal 9.5.7 and Drupal 10.0.7.

When editing an existing Gutenberg Node only a blank page appears. This JS Console logs the following. Please note the mention of "ckeditor5", even though Gutenberg is set as the editor experience.

The https://www.drupal.org/project/drupal/issues/2990907 🐛 JsOptimizer preg_replace gives null as return Needs work is not the case. Tested patch on drupal/core (9.5.9) and issue remaining

Element `gutenberg-loading` is over top menu what is issue by itself ;/

Yey, I found solution for this issue and confirm it can be close for good
I updated from 9.5.9 to 9.5.10 and the issue was gone.

Pleas - after update you need to clear cache.

This is issue related to Drupal Core. Update the Drupal core. Update core.
