That kind of software error isn't really a laughing matter. It might mean your project files are getting corrupted or the program is unstable. You should probably run a check on your software to avoid bigger issues.
Saved my work and cleared the local cache when my design program started doing weird stuff like that. It usually frees up memory and stops the random bugs, idk why but it just works. Had to redo some minor settings but at least the project files stayed safe. Maybe give that a shot before a full reinstall or anything drastic. Just make sure everything is backed up first in case it acts up during the clear. That fixed it for me last time my software went a bit silly with names and stuff like that.
