I have an update on this, for others that might be in a similar position.
The first issue was that a guest had left me a retaliatory review, bringing my rating down drastically as I’m a new listing. Airbnb reviewed the situation and removed the review as the guest canceled their reservation prior to their stay and did not have information to comment on checkin, cleanliness or any of the rating metrics. That was VERY helpful, I think I’m a Super Host now, yay!!
The main issue was different. Airbnb support helped me identify the reason for my sudden suspension. My property was managed by Zeus Living last year, and it looks like they had a listing on Airbnb which had bad reviews. My current listing appears as a duplicate, and duplicate listings are not permitted. I have written to Airbnb clarifying that the other listing is not mine and that I have not had issues or valid bad reviews with my property. I fully expect it to be resolved and my listing to be reinstated, soon I hope.
