Unable to create or edit whiteboards

Question

I just installed Microsoft Whiteboard on my Lenovo Thinkpad Yoga Gen 1, and when I try to create a whiteboard, I get the message "An error occured while processing your request, we encountered an unknown error". When I go back to whiteboard home, I can see that the whiteboard has been created, but I get the same error when I try to access it.

The windows app version is 52.11010.438.0
I am using windows 10 version 21h2 build 19044.2130

I have tried:
Restarting device
Reinstalling app
Resetting app
Repairing app

I'm at a loss here and would like to use this app for school
