Hello @michael28468523rvbv,
We understand that encountering technical issues can be frustrating. Would you mind trying to reset Illustrator's preferences as described in this article (https://adobe.ly/3QNVCo9) and checking if it helps?
Disclaimer: Please note that renaming preferences folders will remove all the custom settings, and Illustrator will launch with default settings. You can also save a backup of the folders, the location of which is mentioned above.
Also, try running Illustrator under Safe Mode (Windows / macOS) and share your observations.
Looking forward to hearing from you.
Thanks,
Anubhav
