I have the same issue right now. They sended me yesterday an email that there was a safety issue with one reservation (reservation and guest name NOT mentioned). And because of that they suspended ALL my 6 listings, without any explanation or proof. I have responded immediately on their email, no response until now. I have called Airbnb general line 12 times, No support at all. Just saying please be patient someone will contact you. Now 36 hours further an nobody is contacting me. I'm a host for 8 years and I never had this situation. Also, none of my recent guest contacted me about an issue or wrote a negative review, Nothing! Now out of nowhere Airbnb suspend all my listings with one click without contacting me. This is insane! Please someone here take a look at my account because this Safety team is not responding and the general line cannot do anything.
