You can also use the 10.15.2 Combo Update to overwrite any system software that is corrupt:

Download macOS Catalina 10.15.2 Combo Update

The Combo Update is a fuller install, as opposed to an incremental "delta" update, so it should overwrite any files that are damaged or missing. It does not matter if you have applied it before. It should preserve all your data and settings but that said you should always have a backup.
