there may be options, you might want to look into an Ed visa. Volunteering may also be an option. These options may involve paying an agent and/or an extra fee to get it done, but likely less than would cost you to leave and come back in 2021-2022 or whenever they open again.
If money is no object you can go onto Elite, that's totally legit with no money under the counter but the money over the counter is substantial.
