@Andrew2243 Unfortunately not: they are permanent.
I had a very similar thing happen to me: I had my listing go live accidentally and someone instant booked before I was ready to go. It's the very first review I have as a host. Embarrasing, but definitely not something that has to ruin your listing. I've had about 400 bookings since then: if you're priced competitively in a decent market, you will likely still receive bookings. Take your first few bookings at a lower price, get some good reviews under your belt, and people likely won't even go digging into your profile to see that.
You don't say when you published your listing. Things are just opening back up in England: I would give it a couple of weeks before you get too worried.
There is one alternative, and let me be clear: I don't think it's a very good idea. You could delete your current profile and start again. The problem is that if you get caught by Airbnb you can be permanetly banned.
Also, if you ever need to cancel in future, check to see what can be done penalty-free. Your cancellations might have been covered under the Extenuating Circumstances policy. If you have instant booking enabled, you're also able to cancel bookings penalty-free under some circumstances.
