best method to evolve white snake in bizarre lineage?

what actually happens near the end - does the animation start and then cancel, or does the item just do nothing when you use it? in most of the roblox jojo games the whitesnake line is an item use with a level requirement on top, and the two things that quietly cancel it are being mid-combat and not having the stand fully summoned when you press it. post what the screen says and it'll be easier to pin down.
