Question CKeditor

Sorry, I uploaded the files from my PROD stage. This is where some of my users witness the empty editor issue, but I cannot reproduce it by myself.

I just visited the lang folder in my STAGE site, and here only the english language file exists. I don't know why. Here is the ZIP with the stage language file:

The files are ok. How do you reproduce the error, since you had written that this error occurs for some users, but the editor works for you? I cannot reproduce this error, only a similar one when I remove or rename these plugins.
 

On my PROD site I cannot reproduce the error, but some users sent me screenshots where I could see the empty editor. With my own accounts (admin and a normal user) everything works well.

On my STAGE site I have a test account and I can reproduce the issue with it.

This zip file only contains the English language script. If several languages are installed in Joomla (in your case English and German), these language scripts must also be present in the "lang" folder.
But I think I have found the error. Have you ever created a customckeditor_config.js to change the language? If so, then comment out the code CKEDITOR.lang.languages={"en":1, "de":1}.

No, there is no such line in my customckeditor_config.js , neither in the STAGE (see attachment) nor in my PROD site.

I just copied over the DE language file from the PROD to STAGE, but it did not change anything  

Did you try with Aurelia template?
I see you are using NTS Kunena template. Do you have the latest version?
I use an NTS Kunena template that still hasn't been updated to Kunena 6.2.4 unfortunately and discovered that in contrary to what rich said earlier CK editor isn't working if I disable in customckeditor_config.js

When switching to Aurelia without custom editor file, CKEditor is working like expected.
So it might be template related.......

Thanks a lot for this hint.

Switched to the Aurelia template, now on my STAGE site the issue is gone! I downloaded the latest version of the NTS KBee template, CKEditor is still working!

Let me check this on my PROD site, I'll keep you informed.
