I am happy to share that we have fixed this bug in our latest release – 25.1 which is available worldwide now.
Going forward, our goal is to fix as many top User-Voice bugs as possible and as frequently as possible. Given the nature of the fixes, some of the bugs will take a longer time to fix, but we are on it.

Same here. I'm having the same issue on both Windows and Mac since I upgraded to Illustrator 2021.
Another problem is that when this happens, Illustrator freezes so I have to force quit. After Illustrator and the file are reopened, the last (damaged) version is saved which means that sometimes a lot of the hard work that was done is gone.
Productivity is affected. Please solve this bug as soon as possible.
