I faced the same situation, although it wasn't 'sexual' harassment, just harassment in general apparently.

Basically the company I worked at was taken over and me and some others were forced out. The others rage quitted. I had false complaints made against me, and I was suspended while they 'investigated', I just quit.

My advice would be to walk away. If you know you've done nothing wrong and there's no evidence, you don't want to be in that kind of toxic environment.
