Crash when using "HighResShot" command with Frame Generation enabled on Unreal 5.4

Hi everyone,

I’m encountering a crash in Unreal Engine 5.4 when using the “HighResShot” console command while Frame Generation is enabled. Here’s the crash message I’m getting:

Assertion failed: (TargetTexture->GetName() == L"BufferedRT") || (TargetTexture->GetName() == L"BackbufferReference") || (TargetTexture->GetName() == L"FD3D11Viewport::GetSwapChainSurface") || (5 == 4) || ((5 == 5 && 4 < 1))

[E:\EpicGames\UE_5.4\Engine\Source\Runtime\Core\Public\Delegates\DelegateInstancesImpl.h:518]

It seems to be related to the StreamlineViewExtension plugin. Has anyone else encountered this issue, or is there a workaround to fix this crash while keeping Frame Generation active? Disabling Frame Generation seems to avoid the crash, but I’d like to keep it enabled if possible.

Thanks in advance!

Ok, the issue seemed to come from the DLSS plugin. I had the first version released for 5.4, but I updated it to the latest version (UE5.4_DLSS_3.7.20_Plugin_2024.09.06), and it’s resolved, everything works.
