Hello Perry. Thanks for reaching out. My name is Diana. I'm an independent advisor and a Microsoft fan like you.
It appears that you have saved your document in OneDrive as usual, then you still have an option to get the version of files that is not corrupted through OneDrive version history.
To do that, go to OneDrive.com > my files > locate where your document > right click > version history > check each history that you saved couple days ago and if its open fine without any issue > download it locally then try to open it on desktop.
I look forward to your feedback,
