i have a proffesional rival spreading rumours and gossip amongst colleagues accusing me of criminal actions. what can i do?

Additional information
I have had multiple people who were hired by me to perform at an event I am hosting (i am a music event promoter) back out of my event specifically stating fear of my rival who stated "i will blacklist anyone who works with him"

I have had collegues state they will not support my events due to the "drama surrounding" me.

I am no longer allowed entry as a promoter or as a paying attendee to a certain club that my rival works for. They have taken fliers away from my street team and threatened to "86" them from the club if they tried to promote for my company.

Amongst his claims he has stated he has a video of me stealing money from a club i was hosting an event as well as multiple women coming to both him and the police claiming i raped them but the police won't charge me with anything because "it'd be too expensive to persue". To date, the only claim against me that I have been informed of by the police was by the woman I was dating. Also, the allegations of me stealing are 100% false.
