Editor stucks when start PIE twice in Lyra Sample #555
Description
Describe the bug
Steps to reproduce:
- Create a new Lyra sample project
- Put VRM4U to Plugins folder
- Open the project, open L_ShooterGym (Plugins\GameFeatures\ShooterCore\Content\Maps\L_ShooterGym.umap)
- Start PIE
- Stop PIE
- Start PIE again
Expected Behavior:
The second PIE starts same as the first run.
Actual Behavior:
The editor gets frozen.
