Why my filpbook pause when pawn respawn?

Basic logic:

  1. click button → set bool:death is false → call custom event:set death

  2. custom event:set death → branch → when bool:death is false → update health to max health → call set player spawn location

  3. set player spawn location → set actor location

But when i respawn my character,its flipbook can’t play,it looks pause,and i dont know why.
Like this:
working
cant work

Thank for your help.
