Yes maybe - but do it on a copy of
library, make sure you keep the corrupt library intact :

A Calibre library is the entire library folder - ie the author and book folders, the metadata.db and any other files you see there. You should always backup the library folder and everything in it - yes it takes a bit longer, but if you use something like FFS and you do it regularly its not too onerous.
So, copy that backup of metadata.db into the library copy (overwrite the one that's there) now try to start calibre, if it starts run the Library Maintenance->Check Library function - both phases. The second phase should tell you which books are in the library folder but not in the database.
You could move those book folders out of library and use them as the source to re-add the books
Or you could try running Library Maintenance->Restore database function - warning this may take a long time and it may not solve the problem.

The limits are more likely to be imposed by the file system and the SQLite database, and I think you're a long way short of those.
When you add books to calibre then, depending on the Add Books config settings you have, calibre will read the format files - its always possible that one of the format files has led to the database corruption - I'm not aware that it's ever happened, but with 3.5m active users how would anyone know.
