Maybe change the support floor and roof settings?
It looks as if the two nozzles aren't perfectly aligned in the z direction. If the second nozzle is lower than the first, it will push the support material into the top layer of the part, so it's difficult to be removed, while the distance between the top of the support structure and the underside of the part is too big.
make sure the nozzles are clean and the buildplate is clean where the nozzles touch the bed before starting the print (so the autobedleveling can reach a clean result)

Thanks I will try that. I changed the printcore but it was not much better
