Corupt Lrc Catalog

I cant open up Lrc at all on Windows 11. I've closed the program from Task manager and tried to relaunch from different back ups of other catalogs. Sometimes it attempts to open and says Catalog is corrupt and needs to be repaired. I've tried to locate the .lock files, but there are none in the folder.
