I'm getting the following error

Encountered operating system error 5(Access is denied.) while attempting to read physical metadata.

Lastest search:  Known issue - Sync for data warehouse and SQL analytics endpoint fail in West Europe - Microsoft Fab...

This is suppose to be fixed.  There is workaroud on the page: "Try to retry the sync operation to temporarily mitigate the scenario."  I have no idea what this means or what to do.

We're experiencing this today in East US for a lakehouse and warehouse. Other lakehouses and warehouses in the same workspace and other workspaces are not affected. Simple SELECT TOP 1000 queries take 20+ minutes and return this same error (Encountered operating system error 5(Access is denied.) while attempting to read physical metadata.) According to Microsoft Fabric service status only Asia Pacific is degraded.

Additional Info:  A service principal is the owner of all DB SKUs (Lakehouse, Data Warehouse).

Also, my workspace has been running fine without issues until 7/8/2025.

The ownership of DBs (Lakehouse, Data Warehouse) was a service principal.  A change of ownership to a user principal with admin permission resolved the issue.
