Yes, you probably have broken something.
At this point, my suggestion is to save your data, recreate the database, and reload your data.
You could manually inspect and correct everything in your database, but that’s going to be a significant manual effort with a high probability of missing something along the way or of making a mistake.
In the future, you do want to take the position that you do not want to arbitrarily delete migration files without being aware of all the potential implications of doing so.
