The Canvas Gradebook was loading fine for me at about 4PM yesterday but by about 6PM it would not load. The frame was blank (I could see content start to load but quickly disappear) with the exception of the keyboard shortcut icon, which was non-responsive to a click.

I am blaming the recent update:

https://community.canvaslms.com/t5/Canvas-Releases/Canvas-Deploy-Notes-2023-02-15/ta-p/553929

I am using Safari 14 on Mojave (I don't want to update the OS at this time) which is nominally unsupported but has been working as expected. Also, the Gradebook will load in Firefox 99, which is also listed as unsupported.

I have tried some java console-fu to avoid this change ("set default grade") to the Gradebook to no avail.

Anybody else see this and maybe have a workaround?
