maven cannot access any package in my project - maven

Question

I've tried anything I would find on the internet but nothing seems to work.
I am using Intellij with OpenJDK 17.0.2
The only error is cannot access package for every class in my project
I tried:
Invalidating everithyng and restarting
Restarting my pc
Removing all the repositories in the .m2 folder
Probably something else I don't remember
