Help needed fixing leaking radiator at the bleed screw

Was changing the porous coolant hoses on a 2019 KTM 790 Duke.

Went to refill the radiator, removed the bleed screw as per the manual, noticed it was very hard to remove, as if it were cross-threaded (not the first bolt/screw I found to be cross-threaded on this bike..must have been assembled by Arnold :().

Yup, you guessed it, the radiator now has a small leak from the bleed screw.

BTW, is it normal for the bleed screw not to have a gasket/washer?

Bike is still in warranty, not sure if this is covered so need help fixing this.

More head - less ass
maybe throw in a copper washer and save a trip to the dealer?
Otherwise, yeah. Warranty fix.
Not sure about the 790 but there's a burping procedure that involves getting the bleed screw to the highest point and getting the motor up to temp.
