Unreal Engine Crashes When Playing Levels in ZEDSamples Project

Software Unreal Engine
1

I recently received my ZED2i and set it up to use with the Unreal Engine plugin. While the diagnostic tool shows green checks across the board and all built examples in samples/bin work perfectly, the Unreal Engine crashes instantly when I try to play any level in the ZEDSamples project.

As I work with Unreal it’s Visual Studio is already set up as required (I’ve also double checked)
I’ve tried both with CUDA12.1 and CUDA 11.8 ( Completly reinstalling the correct ZED SDK after installing it)
I’ve tried with 5.3 (with the latest plugin) and with 5.4 (with the 5.4 branch of the project)
I’ve tried with the optimized models and without.

The issue seems similar to issue #35 on Github, but that was a couple of Unreal Engine versions ago.

Here’s the log:

I can’t upload the diagnostic file as I’m a new user! If you could lift this restriction I can upload that also (if it can help)

Hi,

Can you please tell me what ZED SDK version you are using ?

Thanks.

Thank you for you quick reply!

I’m using the latest available, 4.1.4.
As I went to check I realized it was published yesterday! Is there any place I can get older versions?

Here’s also the Diagnostic Results:
