Hello Steve Isaacs,
Welcome to Apple Support Communities!
We're here to help with the Freeform app.
Let's try starting in safe mode and see if you get the same results.
Once inside safe mode, log in to your account and check if the issue is also occurring or not. Use this article for the steps to get into safe mode: How to use safe mode on your Mac
If everything is working properly in safe mode, but then is not working after you restart the Mac, please check the section titled "If an issue doesn't happen in safe mode" for the next troubleshooting steps.
If the issue is also happening in safe mode, you will need to see if this problem occurs in a new test administrator account on your Mac. A test user will let us know if the issue is isolated to your account, or system wide.
Change Users & Groups settings on Mac
Let us know if you have any questions.
Thank you for using Apple Support Communities.
Take care!
