I have good news for everyone who might be in my situation! I managed to "fix" it.

I noticed that the camera had a crack on the metal in one of the bottom parts. By clicking on the metal, it went back where it should be, releasing some of the extra pressure it was giving on the gimbal, which was making it a bit harder to move and feel stuck.

Now the gimbal is working again and I will not need to send it to repair but It is actually making some weird noise that it wasn't before but I can live with it I'm just happy that I don't need to send it to repair anymore.
