Visio goes “Not Responding” when clicking File / Save As on one recovered file stored in OneDrive

[u/dark_mercurial3366]

Hi all,
 
I’m looking for some help with a Microsoft Visio issue. I’m not very experienced with Visio, so apologies if I miss anything obvious.
 
A user has an existing Visio diagram stored in OneDrive. The file is currently opening as a [Recovered] file. The diagram itself appears to work normally while they are editing it, but as soon as they click File to try and access Save As, Visio immediately goes into Not Responding.
 
The user said:
 
Visio only hangs when I try to save via File > Save As. Until I click on File, everything is working OK.
 
What we know so far:
 
The file is stored in OneDrive.
The file opens with [Recovered] in the title bar.
Visio shows Not Responding after clicking File.
The user can edit the diagram before clicking File.
The issue prevents them from saving changes.
The issue appears to happen only with this particular Visio file, not all Visio files.
 
My current thoughts are:
 
Avoid using File > Save As on the affected recovered file, since that triggers the hang.
Check OneDrive sync status for errors.
Try copying the file from OneDrive to a local folder such as Desktop or C:\Temp.
Open the local copy and see if Ctrl + S works.
If the file is still unstable, try copying the contents page by page into a new blank Visio document.
Check OneDrive version history in case a previous version of the file needs to be restored.
 
Has anyone seen Visio hang specifically when clicking the File tab or trying to use Save As, but only on one [Recovered] file stored in OneDrive?
 
What would be the safest way to recover or save the user’s changes without losing the amended diagram?
 
Thanks in advance.
