Banks don't care if you paid taxes. Most of major banks will close your account if they suspect crypto-related transactions. And almost all fintech companies will ban your account if you even just buy crypto with a card payment: Wise, Monzo, Starling, etc.

crypto-related transactions is a different thing from banning banks from dealing in crypto. If banks don't want to deal with the Due-dil that's fair & fine to me. You don't need a bank to use an exchange.

I believe revolut operates in the UK and allows you to trade in btc.

And what do you suggest to use? Trade crypto to cash? And then how will I put said cash on bank account without getting on check list?

In UK even if you have 1000 GBP in cash they look at you like you're drug dealer.

Revolut itself is shady and at least until recently didnt have or used any banking license in UK. And it's can ban you at any moment for no reason.
