I'm using Backdrop v1.30.0 with CKEditor 5 Version: 44.1.0. All has been swell so far. Suddenly, changes I have made in the editor are not preserved after saving (other changes to other fields are saved). Additionally, nothing happens now if I hit the 'source' button. Earlier today, the word 'source' for the toolbar button was inexplicably replaced with 'expand.' When I clicked it, it changed to 'collapse,' but did not do anything and still did not switch to viewing the source. What might be causing CKEditor to misbehave? What can be done to fix it?

CKEditor 5 Not Saving Changes, Can't Access Source
You can edit images and load them back to the same folder with the same name and extension, this will not create a problem. Replace directly in the file system, without the use of CMS, for CMS...
Image manipulation on server?
I was under the impression you could not do that - don't know where I got that idea from... thought it had to do with the way Backdrop manages image files.

This may be a Javascript error (the fact that the source button doesn't work may be an indication of this). Can you check the browser's console after opening the edit form and after clicking Source, to see if there are any errors there?
Thanks. I don't spend much time in the console. Yes, there is an error message.

And upon clicking the source button, there are more error messages.
I used the new Chrome AI console 'understand this error' helper which provided the text in this document. It did give me a hint it might be something to do with an image. I am dealing with content that is being imported from a Drupal7 site and the issue does not affect other content.
It was the image. I deleted it and the problem went away. Whew.
I'm experiencing the exact same issue. I have no idea what's causing the CKEditor to fail but my developper console is full of the same error messages that Chrys reported.
Essentially the changes no longer save and the "source" button no longer works.

I note from https://github.com/backdrop/backdrop-issues/issues/6904 that "DLL builds are sunsetting", which makes me wonder if there's a correlation there.
On top of that I'm having issues with the tarteaucitron library which means the GDPR Cookies module no longer works. It's giving me a 403 ERR_ABORTED error however the init_tarteaucitron doesn't display a permissions error but obviously since it relies on the main library it doesn't work either. I mention it here because both seem to be JavaScript errors so there's a chance they may be related somehow.
I note that the latest Backdrop core update included an update to the CKEditor so something there must have triggered an error.
