Startup Script Error Illustrator

Problem with Adobe Illustrator.
For about a month now, Illustrator has been reporting an error, which can be seen in the image. Furthermore, when saving some data, Illustrator crashes and it is not possible to save the data in it.
I can't save colors to the library as before. The library does not record the color at all. We tried to uninstall the whole program and reinstall it, the problem still persists. Using an older version also didn't help. Please advise how to solve this. Since I use the program to work and I need to work with it as quickly as possible this error bothers me a lot.
Please do not refer me to other discussions, I did not find my problem in them. Thank you
