The block editor menu havent the "editor"

Does the Einfaches HTML text format have the CKEditor enabled?

Yes the ckeditor 5 is enabled:

Are there any browser console errors?

I look at the chrome console.

I hope, that is what you think about.

But look

Which themes are you using? Can you please export your editor.editor.basic_html and editor.editor.full_html config entities and attach them here?

Right now, the steps to reproduce this problem are missing. It's impossible for us to help you.

Now I have the Claro → theme, the same.

Before the bootstrap5 3.0.7 → theme.

The files what I have found for the search "editor.editor." are:
editor.editor.format_1.yml
editor.editor.format_2.yml
editor.editor.format_3.yml
editor.editor.gutenberg.yml
editor.editor.eu_test_text_format.yml
editor.editor.basic_html.yml

Do you need the other files also?

The expand console messages...

The console errors would be more readable if you disable JavaScript aggregation, rebuild the cache and check again.

Without javascrip and cleared cache, there isn't something in the console errors

Without JavaScript aggregation, correct? Does the editor appear in that case?

uuups, forgot to reload the page...

now the message:

GET https://excample.com/core/themes/claro/images/menu-expanded.png 404

s_QjckxYY7d65OkDZ_kKnspyGUlRI9mSC-aM4xmMhrTbg.css:1

Now I change the theme to the bootstrap5 3.0.7, there isn't the 404 error. The console are white

I suggested disabling JavaScript aggregation, not disabling JavaScript.

ok, now the lines

It sounds like this issue is a duplicate of 🐛 Aggregation breaks CKEditor 5 Closed: duplicate .

Can you confirm? In other words: does the problem ONLY occur when JS and CSS aggregation are enabled? (And not when they're both disabled?)

Aggregation is still enabled in comment #16.

yes Wim Leers → , that is the Issue 🐛 Aggregation breaks CKEditor 5 Closed: duplicate

thanks

Now I disable css and javascript aggregation at /admin/config/development/performance 🐛 Library order asset weights do not work properly when a large number of javascript files is loaded between two jQuery UI libraries Fixed that is from https://www.drupal.org/project/drupal/issues/3222107 🐛 Library order asset weights do not work properly when a large number of javascript files is loaded between two jQuery UI libraries Fixed

And the menu from the ckeditor 5 is there, at all editor types!

Interesting observation, @FvD! 😄 👏

You said in #3 you're on 10.0.8.

But 🐛 Library order asset weights do not work properly when a large number of javascript files is loaded between two jQuery UI libraries Fixed did not ship in a release until 10.0.9! See https://www.drupal.org/project/drupal/releases/10.0.9 → .

Can you please try updating to 10.0.9, clear all Drupal caches, clear all browser caches and then report back? 🙏

Wim, it works fine!😀

1. I update drupal to 10.0.9
2. switch java and css on: /admin/config/development/performance
3. flush all caches

4. Look at the blook editor page, and it works!

Great! 🤠🙏

Excellent!

So this was an unrelated core bug causing this, fixed since Drupal 10.0.9. Yay! 😊

Thanks for all your help and patience, @FvD!

Congrats on your first Drupal core issue credit! 😊

Thank's @Wim Leers 🤠🙏
