Description

Reproduced 3/3 times, issue also occurs in //UE5/Release-5.0 - CL 20979098 Binary. Confirmed NOT a Regression.

Steps to Reproduce

Create a new 3rd person template project
Open Animation Blueprint ABP_Manny
Right Click anywhere in the event graph and add a Get Enhanced Input value node
Attach a print text node to the end of any of the end nodes, and print the value of the EI node
Compile
PIE in default level

Actual Result: Crash

Expected Result: No Crash
