Solved
I'm working in the browser, and am unable to save any activity that includes any applet. I'm able to save text just fine. I can add applets using the +ADD ELEMENT menu, and they appear to work fine, but when I hit SAVE or SAVE AND CLOSE, I always get the error message err_lost_backup. I've tried multiple browsers, private windows, and disabling any extensions. I've started the activity from scratch a number of times and tried multiple applets, and always get the same error. If I try to download the activity to my computer, I get only the saved part. I can't find any search results with this error. Any ideas?
I'm using a Mac with an M1 processor and MacOS 11.1.
I made a brief video showing the error:
The same problem 
I'm afraid I can't help but I have the same problem.
Texts, videos and weblinks are just fine. I've narrowed the problem down to pictures, Applets and PDFs. As soon as I add one of those formats it won't save (err_lost_backup).
My rather clumsy solution to this problem:
When I copied the activity, I was able to include and save two or three pictures/applets before the error message popped up again. So, I finished the project with lots of copies. However, that's why I guess that my data can't be the problem here.
