Lightroom Classic Unexpected Error Opening Catalog

When I try to open Lightroom Classic I get the Following Error:  Unexpectrd Error Opening Catalog  The catalog could not be opened due to an unecpected Error /"Try Again"/"Choose a Different Catalog"/"Exit."  I tried "Try Again" with no luck so I tried "Choose a Different Catlog," a Window opens giving me the option to "Choose a Different Catalog" / "Create a New Catalog" or "Open" the Lightroom Catalog.Ircat listed. It doesn't open so I tried "Choose a Different Catalog;" another window opens with a list of Folders; Lightroom Catalog Helper.lrdata, Lightroom Catalog Previews.lrdata and Lightroom Catalog Smart Previews.Irdata and a Dozen Lightroom Catalogs. I tried opening the folders, but they just keep opening to other folders til I get to an empty one. So I tried opening the Catalogs and get the Same Error: Unexpectrd Error Opening Catalog  / The catalog could not be opened due to an unecpected Error / "Try Again" / "Choose a Different Catalog" / "Exit." The only other option is to "Create a New Catalog" which I tried, if I choose an existing catalog it asks if I want to replace the existing one, but I get "Cannot replace..." when I try to Create a new one a window opens giving me the option to choose a file from my pictures, but doesn't let me create one. I get the same Error no matter what I choose. If anyone else experienced this and was able to fix it I'd appreciate Any Help.  I've attached a Lightroom Catalog, maybe someone can open it or let me know why I can't. Thanks.
