Issue started around the same time for me too, on the 8th. I had a ticket with UiPath and they directed me to install Fiddler that helped troubleshoot.

From the logs I saw that the request was failing when trying to reach a sharedwithme folder. I tried unchecking Shared from the Microsoft Office 365 Scope, but what solved it was adding a subfolder in the Find Files and Folders activity.
