Just pick a junior job in some boring corporation, or startup with shit salary, and go from there?

The world is in desperate need for more good engineers. Every company I worked on always need more engineers. Especially now after COVID, the industry is doing great. It's not hard to find jobs now, even with no degrees.

Of course you need to lower your expectation, maybe you will work in some CRUD-shitting factory for a while, or work on some cryptoblockchain nonsense, but it's still an experience?

edit

also that arts bachelor sounds fun to be honest. And it can be useful if you decide to go, say, FE/full stack route. Or go more into UX/UI.
