--- Comment #12 from MWATTT <megwattt at gmail.com> ---
I just compiled the Scifi Hallway demo with Unreal Engine 4.22. I have the same
issue so it probably affect all UE4 applications using vulkan.

This time, I have some info from the log:
"Assertion failed: Images.Num() == NUM_BUFFERS
[File:D:\Build\++UE4\Sync\Engine\Source\Runtime\VulkanRHI\Private\VulkanViewport.cpp]
[Line: 610] 
Actual Num: 5"

I'll attach the full log.

With UE4.22+, using "-vulkanpresentmode=0" also solves the crash. (Does not
work with Supraland, as it's a UE4.21 game)
