Description

Reproduced 3/3 times, issue does not occur in //UE5/Release-5.0 - CL 20979098 Binary. Confirmed Regression.

I've tried enabling the Media Movie Streamer plugin & Electra Player plugins, but Game crashes the same regardless.

Steps to Reproduce
  1. Create a new Blank Project
  2. Go to Project Settings>Project>Movies
  3. Add 2 Startup Movies (any mp4 files should work)
    1. Click "Wait for Movies to Complete" to ensure all movies play
  4. Start Standalone Game

Actual Result: Game freezes on last frame of 1st Movie, then crashes

Expected Result: All Startup Movies should play
