Microsoft Access gets "Cannot open Database" when trying to open multiple partitioned table

2019 Advanced - Sales order history detail has extended into a second partition and MS Access now gets the message

"Cannot open Database" when trying to link or import the table. It may not be a database that your application recognizes, or the file may be corrupt.

I rebuilt the table and used "Integrity Check", but this made no difference. Has anyone ran into this and found a solution?
