Reading from texture doesn't work in packaged build (5.1)

I’m trying to read pixel from UTexture2D and it works in the editor but in packaged build I’m getting a blank color and a bunch of errors. Here’s my code:

FTexture2DMipMap* Mip0 = &AreasMap->GetPlatformData()->Mips[0];
FByteBulkData* RawImageData = &Mip0->BulkData;
const FColor* PixelData = reinterpret_cast<const FColor*>(RawImageData->Lock(LOCK_READ_ONLY));

// Access the color from PixelData here

RawImageData->Unlock();

Here’s the error:

Additionally every time when the provided code is called I’m getting this:

same issue here, have you find a solution?

You can draw a material with your target texture to a render target and then save it as an array. That’s how i did it in the end.

UKismetRenderingLibrary::DrawMaterialToRenderTarget(this, MyRenderTarget, MyMaterial);
TArray<FColor> PixelData;
UKismetRenderingLibrary::ReadRenderTarget(this, MyRenderTarget, PixelData);

I have the same issue but with pure blueprint project. The error happens when I try to add ARCandidateImage in the ARSession.

Somebody have an idea to resolve it ?

I explaine this in this topic : How to use "AR Session" and "Add Runtime Candidate Image" with Blueprint ?
