Praxis e cranks stuck crank bolt

Hi,

The crank bolt of my non-drive side ETOR Praxis crank arm is stuck. It’s a new bike, though the crank arm was installed 2 years ago (I bought a 2023 model this year).

On my DUB cranks I was able to get the bolt loose using Dave’s method involving a breaker bar and a pipe around the other crank arm.

On this crank, the bolt is starting to deform, but I’m not getting it to open. What should I try? Heat? Hammer blows on the breaker bar? I don’t think i can reach the threads with WD40 because of the shape of the bolt.

Thanks for tips
