SpawnEmitterAtLocation empty Return Value

It works in 4.24, but in 4.25.3 i get this Error. If i deactivate AutoDestroy, has same Error.

Blueprint Runtime Error: "Accessed None trying to read property CallFunc_SpawnEmitterAtLocation_ReturnValue". Blueprint:  Spieler Function:  Execute Ubergraph Spieler Graph:  EventGraph Node:  Bind Event to On Particle Collide

EDIT: The first or last particle is spawned. It’s available in a ForEach loop. Maybe it cannot bind all the particles in one loop.
