Hey @jeff33, thank you for reaching out!
Can you let me know if this is happening in the browser, desktop app or both? Did this happen in a specific file or in other files too?
Can you try clearing out the cache. Here are some information to troubleshoot: https://help.figma.com/hc/en-us/articles/360040523973-Troubleshooting-checklist 1
Also please try to force-quit and open Figma in a new browser window (or force-quit the Figma Desktop app and restart it.)
Could you please try to restore from a previous version? You can find the steps in our Help Center article: Restore a previous version
Thank you for your help in advance!
