Catalog issue with PSE Bundle 26 and Tahoe 26.2

I successfully converted from PSE 24 to PSE 26 with a catalog of 211,000+ objects.  Everything was good.  However, the name of the converted Catalog was "2024 Catalog 1" which was not to my preference.  I followed Adobe's advice for how to rename - and have done so to "2026 Catalog 2" - as this was my second attempt to cleanly rename.  Well after the rename - every time I enter Organizer, I receive the attached error message - which I can just bypass - and open the catalog normally from the Manage Catalog Dialog Box.  I've tried to Optimize the 2026 Catalog 2 (that worked fine), yet I still get the annoying error messge even after the optimize.  I'd prefer to maintain one catalog (more effective searching) - if possible.  It seems to me that the Rename feature introduced a problem into the 2026 Catalog 2.  Any advice?
