Hello Laurie Wagner-4636,
Thank you for your question.
Initially I believe that this is a punctual bug, because so far this failure has not been reported in our forums.
But, here are some suggestions on how to fix this:
1) Repair or Restore Paint application
Step 1: Go to Windows 11 Settings > Apps > Apps & Features > scroll down and search for Paint
Step 2: Click on the 3 dots next to it and select Advanced Options > scroll down and select Repair or Restore.
Step 3: After that restart the device and check if the problem persists.
The other option is for you to report this problem to the Windows 11 team, because that way you will receive more detailed guidance on how to fix it.
To do this, access the link below and in the top menu select "Ask a question" and describe the entire problem, including images if possible:
