User Microsoft 365 Apps Freeze when Trying to Save

Having a strange issue with one of our users when using Microsoft 365 Apps on a Windows 11 system. The original behavior reported was when he was trying to save a document to OneDrive. He gets a processing box but it never completes and the app freezes. Then he noticed if you just did a Save As from any of the Office Apps you get the blank page and the app freezes. Sometimes a reboot resolves the issue but only for a short time. 

Here are some items we have tried to this point:

Have tried pausing synching in OneDrive

repairing office 365

Reinstalling office 365

Saved to downloads > Can reopen document but when trying to save as again the page is blank. Will either have to force close in task manager or let it sit until "waiting for another application to complete an OLE action" then closing

Pausing auto save to cloud in word/outlook/excel

Disconnecting the OneDrive sync and re-connecting seem to work at first but after an hour or so we saw the same behavior.

We decided to set him up on a brand new system and after we set things up the issue followed. We are seeing the same behavior on the new system. 

One item of note is we have a third laptop which has an old version of Office using the ODT installer which is working fine with his account. The other two laptops that are failing have the latest Office 365 software downloaded from the portal.

Not sure if this is an issue on the backend with his account or some other type of issue. Just wanted to see if anyone has ran into this issue before. 

Thanks.
