Intermittently, Illustrator does NOT save the file.
Intermittently, when I save a file (using Ctrl-S or File > Save), the existing file is NOT saved. This has caused me to lose work.
The Illustrator UI thinks that the file has been saved - the File > Save option is greyed out. When I look in the file's location on disk, the existing file shows an older file date and time; the last time it saved successfully. There is a new file with the expected date and time and the extension "t".
I can do a "Save As" which works. I can make some trivial changes the the file, Save, and that usually does save the file correctly. But the failure to save normally still occurs about 25% of the time. It's been happening since I installed Illustrator.
I am working with .SVG files in Illustrator 22.1 on Windows 10.

I have been losing work in illustrator since updating to Catalina. It has caused me a lot of anguish. I think I am saving the work as I go then it crashes and I lose hours of work.
