I'm having an issue with my controller not working on the PC version of the game. And I wanted to how to fix that.

have you rebinded your controls?

How do I do that?

should be in the options menu

It is much more complicated than that. If you aren't in the lego discord I would recommend joining that. In either case, you need to run the game through steam (more controllers are compatible that way). The PC setup guide will help you with that. Then you just add your controller and start the game. Should work after that.
