I started getting this error after I changed a collection type to a single type.
I have tried to revert to a working comitt, getting rid of the database I’m using, reinstalling strapi, replacing my node_modules@strapi folder with a copy of a coworker’s , reinstalling strapi again, and reinstalling node.js

This can be closed or deleted, I solved the problem I was having.

Can you please share how you fix it? I’m running into the same issue.
