XD stuck on loading cloud file. Tried opening file once exported as local file, get error 86
I have a file saved on the creative cloud. A few days ago, I experienced zero issue opening/saving the file. I haven't opened the file till today.
The loading bar would progress quite quickly...to a certain point. Even after 10 minutes, the loading bar didn't change.

I thought maybe I needed to update my OS and XD. Did that. Currently on XD v31.0.12.23, and macOS Catalina v10.15.6. Restarted my laptop. Loading bar would still get stuck.
Reinstalled XD. Same ending. I don't know if it's considered crashing on my mac, since my device never indicated that the XD was not responding when I right click on the dock icon.
I then exported the file as a local file via Creative Cloud > Your Work, and tried opening the file from there. Loading bar didn't get stuck, except I got the error 86 message that said "This is not a valid XD file."
As I don't have any other devices to test whether it's just my laptop or the file, I then tried duplicating the local file and gave the new file a different name. Same error 86 message.
This is quite frustrating. It just seem the software is a bit temperamental - one day everything works beautifully, and then another day I can't even open the file.
Can an Adobe team member assist please?
