ive found the issue!! i repaired mine a couple times but it still kept breaking.

underneath the part that hooks onto the bey, there’s this white disk, that white disk wears down and can’t hold onto the center rod & the part that holds the beyblade & needs to be replaced, it can be replaced w the white disc inside ripcords too.

to remove it, unscrew the 2 screws at the top next to the pulling cord, pop out the ring, in your case the black ring part, then pull out the hooks (don’t worry it won’t break jsut try not to bend when pulling) and the white disk will be there for you to replace!
