I have this large c++ code that works fine on 5.5.x but after migrate to 5.6 I got a startup crash on editor when using directx12.

I found it.

Its caused by bink. I have a widget to play videos using bink that works fine in other engine versions but now iwth 5.6 specific directx 12 its crash the editor with E_INVALIDARG command.

Looks like dx12 implementation are missing something from bink api maybe?

Same here

UE 5.6.0
GPU: RTX3070

I need to remove the Bink plugin or switch to D3D11 to open the Engine normally.

lifesaver! I was already thinking about abandoning idea of updating my old game running on UE 5.2

But also interested in how did you found the cause of issue? I could use it for the future

The log/crash log didn’t contain anything about bink at all
