dishuman commented 4 years ago

I am using UE421.

When I switch videos(via blueprint at runtime) few or 10-20times, some times UE will crash. and here is the crash log:

Integer divide-by-zero - code c0000094 (first/second chance not available)

This is still an issue when switching between videos to quickly. Our workaround is to force a 0.5 seconds delay between closing/opening videos which works fine for our use cases.
