Document Won't Load (Keeps Asking to Refresh)

One of my documents keeps loading only for a little window to pop up and say that it requires an update and to refresh it, but every time I click on the "Refresh" button, it only keeps loading--sometimes indefinitely; sometimes, the same window pops up again, with no results. It's only one document--I can access my other files just fine. Its thumbnail also won't load; it's either indefinitely a light grey with a white sheen sliding by, indicating it's loading, or it results in a blurred darker grey with a dark grey file symbol. Again, the thumbnails for my other files are fine; it's only this one that won't load.

I made a duplicate of it to try and see if that would somehow fix it, but the same things are happening to it. The same issues not only apply to my browser but also the desktop app.

I restarted my laptop also, but no dice.

I don't know how to find the version the app is, but I'm using a Windows 11 laptop and Google Chrome as my brower along with, again, the desktop app.
