EDIT 2: The problem was finally solved starting a new project and copy-pasting all the code I had in the original one. I still don't know why this happened, but if someone has a similar error as mine, keep in mind you can "solve" starting from zero and copy-pasting everything (and, of course, re-doing all composer require you were using).

Finally, I solved this by creating a new project and copy-pasting all the code I had in the original project. Then reinstalling all need components using composer require.
More information is in the second edit of the question.
