That's quite old thread Event ID 25 from source MSOLAP$LocalCube (microsoft.com) if something could help from it.
I'd check first if Power Pivot (data model) works on any new file - create simple source table, build PivotTable adding data to data model. If doesn't work perhaps you need to repair the Office.

Tried to add data to data and I get the MSOLAP error message. I will now do a repair of Microsoft 365 and see if that will clear the error message.
