Unfortunately troubleshooting crashes isn’t always this cut and dry to troubleshoot.
Sometimes a level with lots of meshes/materials isn’t crashing because of an issue with those particular assets, but because the GPU is being overwhelmed and now crossing a threshold of stalling or crashing.
Im having the same issue and the crash logs just state a generic GPU crash. But after changing from DX12 to DX11 i seem to have more fps, my GPU isn’t having huge 100ms stalls when running trace files, and now the crashing is gone…
