What Lightroom app are you using? Lightroom (Desktop), Lightroom Classic?

When you use the term Collection, that is a term used in Lightroom Classic.

Assuming you are using Lightroom Classic, the catalog could have been damaged. Try one of your backup catalogs. If you have been using the Lightroom Classic backup function, those backups are .ZIP files and have to be unzipped before you can use them in Lightroom Classic.
