Before anyone gives me the basic advice... here is what we have already tried.

Calling QB support

Updating QB and Office

Disabling Add in's

Disable VBA macros with notification

Revert to a previous version of office when it used to work.

Fix data damage

Complete reinstall of Office.

This issue happened back in 2023 after an update. Didn't get resolved till QB updated again.

Quickbooks, you need to fix this
