ArcGIS Maps SDK Crash on 5.6.1 Linux

[PaulAmbrosiussen]

I am getting this crash on project startup on Linux when using the ArcGIS Maps SDK on Linux for Unreal 5.6.1.

My NVIDIA driver is 575.57.08. Happens on multiple machines unfortunately.

Am I the only one, or is this a known problem?

I can get the editor to no longer crash on startup when modifying the below two files where it crashes:

ArcGISMapsSDK/Source/ArcGISMapsSDK/Internal/ArcGISMapsSDK/Renderer/GPUComputing/NormalMapGeneratorShaders.h
ArcGISMapsSDK/Source/ArcGISMapsSDK/Internal/ArcGISMapsSDK/Renderer/GPUComputing/ImageComposerShaders.h


// Create vertex buffer using modern UE 5.6 API
FRHIBufferCreateDesc CreateDesc = FRHIBufferCreateDesc::CreateVertex(TEXT("FNormalMapGeneratorGlobalViewModePSResources"), sizeof(FNormalMapGeneratorElementVertex) * 4);
CreateDesc.SetInitActionResourceArray(&Vertices);
VertexBufferRHI = RHICmdList.CreateBuffer(CreateDesc);

 
But then when loading a map that contains ArcGIS Maps SDK layers, I crash on:

Any other map without any ArcGIS Maps SDK components works perfectly fine.

Thanks for reporting this. We have included a fix for this in our new version that was released today. Please let us know if you are still having any issues. 

Also, we tried the workaround that you mentioned as well and couldn't reproduce the crash after that change.
