"iCloud has stopped responding", PC, Win11?

For the past few days I've been getting this error message every time I try to open iCloud Mail on my Windows 11 PC (using Firefox):

ERROR CONTEXT
undefined


Pressing either "Close" or "Send to Apple" seems to do nothing, as the page just refreshes and then the same thing pops up. Behind this error notice, I can see all the new emails I got sitting unopened, so it seems as if everything loads in perfectly fine but because of this notice I cannot actually use my mailbox.


If anyone knows of a solution for this I'd really appreciate it.

Windows, Windows 10
