React: failed to compile // webpack problem

Question

My project can't be compiled anymore. It came suddenly, I didn't get why. It seems to be related to webpack. Maybe I need to downgrade webpack the version before 5 but I don't see how to do it in React. I managed to reduce errors from 90 to 7 with adding resolve:fallback but I don't know what to do with others. So, now I have these errors:

Failed to compile.

Did you mean './module'?
Requests that should resolve in the current directory need to start with './'.
Requests that start with a name are treated as module requests and resolve within module directories (node_modules, /Users/yulia/Documents/DEV/JS_REACT/projects/arrosy-moved/node_modules).
If changing the source code is not an option there is also a resolve options called 'preferRelative' which tries to resolve these kind of requests in the current directory too.
