Is my crank ruined?

MTB noob

I want to change my crank to a higher grade one but the problem is that i have cross-threaded the bit where the crank extractor tool is supposed to go. (3pc crank with square taper)

Is there any way of removing the crank or bottom bracket or do i have to buy a new frame as well?

Cut a slot in the arm to relive the pressure caused by the taper and it will come off.

Go for a ride with the bolt out the pressure will cause the arm to finally come off.

Angle grinder through the axel.

So there is now easy way to get out of it. I can do any of them and ill have a go at the second one to start with.

Or remove the bolt and smash it off with a hammer (easier if you use a bar as a drift), it's scrap anyway....
