Unreal Engine Issues and Bug Tracker (UE-22874)

Description

Adding a text render component to a blueprint through C++ at runtime crashes the standalone player. It does not have any effect on PIE. Also, this only seems to occur when the blueprint in question is being spawned into the level on a key press using the Spawn Actor from Class node.

After multiple tests, it was determined that the cause of the crash was the addition of a Text Render Component inside of a Scene Component-based c++ class. Adding a text render component to an Actor-based class did not cause any issue.

Found in 4.9.2 binary, and reproduced in 4.10 Preview 3 and Main CL 2749677

Steps to Reproduce

1. Open test project
2. Launch the game in standalone
3. Press "G" to spawn an instance of the blueprint

Result: Editor crashes

Expected: Blueprint would spawn successfully.

Callstack

Unknown exception - code 00000001 (first/second chance not available)
