My blueprint is crashing when i use level blueprint

I have a openable door bp
When player overlaps with doors collision player start tracing and if trace hits the door the crosshair pops up
it is works perfectly fine but when i add any node on my level blueprint the code dont work and says this

“PIE: Error: Blueprint Runtime Error: “Accessed None trying to read property NewVar_2”. Blueprint: FbxScene_portmanto Function: Execute Ubergraph Fbx Scene Portmanto Graph: EventGraph Node: Crosbuyu”
this is my doors bp:

:

this is my crosshairs bp

Basically click the word on the far right hand end of the error, that’s the node giving you the problem. You’re passing it nothing.

I tried to replicate this problem but it works fine on my end. Either your “Crosbuyu” and/or “Croskucul” functions are getting called before the “new var 2” variable is set, or that variable is set to null because your WidgetBP is not created at that point in time.

It was working fine on mine too but when i add a node in level blueprint it gives error also when i go my door’s bp and change anyhting like any boolean value it works fine again
