Hello @MM-Brian,
Sorry for the late response and the crashing. I hope the issue is resolved by now. If not, I would request you to share a few more details like:
- The exact version of Illustrator
- Have there been any recent changes made to your computer (OS Update/ Antivirus/ Plug-Ins)?
Additionally, you may try updating Illustrator to the latest version, launching Illustrator under a new Administrator account on your computer, and check if it works. If yes, kindly try manually setting the permissions for the preferences folder by following the steps in this article:

Kindly update this discussion if further assistance is required.
Thanks,
