Whiteboard resizing when I use the toolbar

[DMS3]

When teaching my math class, I always screenshare the classic whiteboard because it's bigger. When I click the toolbar to erase what I wrote, the whiteboard minimizes by about 30%. This just started today. If I want to change the ink color, nothing goes wrong. Touching my pen to anything I usually do on that toolbar minimizes the whiteboard every time.

I just uninstalled Zoom Workplace Pro yesterday in order to update it via reinstalling. That's because the update instructions use features I don't have. I repeated that process this morning to no avail.

My version is now 6.2.3 (47507) on a Dell Inspiron 3793 laptop (Windows 11).

Is anyone else having this issue?
