Second gap year?

I started at LSE this year but midway through first term decided I wanted to do a gap year so suspended my studies - due to Covid I haven't had a "proper" gap year. I have the option of either starting again at the beginning of next academic year or taking a full year out and starting in 2021. Do you think starting Uni at 20 will make it awkward socialising with people 2 years younger and do you think the negatives of taking another year out outweigh the uncertainties of starting in Sept 2020.
