[Resolved] EXCEPTION_ACCESS_VIOLATION reading address 0x0000000200000004

[unit23]

Yesterday, when building in 5.3.2 I came across this error while having no internet connection.

What I did to resolve this

• Waiting for internet connection
• Fixed up redirectors, since files were deleted via the Force Delete option and this may have resulted in the assert.

While deletion of the Intermediate folder worked sometimes - no error during build. The likely reason for above errors are the moving of the CitySampleCrowd folder, deletion of all the CityCrowd blueprints (which were not in use) appears to have resolved the issue now finally.

The problem again surfaced, after carefully reading the output look I’ve noticed this warning

LogD3D12RHI: Warning: Descriptor cache ran out of sub allocated descriptor blocks! Moving to Context local View heap strategy

Increasing heap size can be done see the following post

Increase device global heap size - (DirectX 12)

So got this error and some stuttering in game. I increase those 2 values to 1.000.000 ( from default 500.000) . And it fixed it. I am not 100% sure about the detail under the hood of this DX12 implementation thought. Adding this to DefaultEngine.ini [SystemSettings] D3D12.LocalViewHeapSize=1000000 D3D12.GlobalViewHeapSize=1000000

The project builds again without critical error, so this random heap related error suggests that there is a problem with the VRAM. Hopefully increasing the heap size can resolve this issue now.
