Engine crashes after shader compilation finishes

[ManlyGaming1]

Every time i open my project it compiles shaders, freezes for a few seconds, and then crashes with this:

Unhandled Exception: EXCEPTION_ACCESS_VIOLATION reading address 0x0000015f384505d0

Hey there @ManlyGaming1! Welcome to the community! So this is a memory error stemming from nvwgf2umx which is related to GPU drivers. Since this issue can be many different things, I usually point people to the most recent thread with compiled fixes. (Sorry it’s a bit of a link hop, but everything we reference over there are workarounds for some fixes for others). We’re also still solving a rare case in that thread where most of the fixes didn’t work. The most recent from GraemeVR near the bottom is still being tested.

3D Model is crashing UE5 when opening Level

The Level is blank besides the model, so I’m assuming it’s the model. I exported it from RC and have a 3070 GPU / AMD Ryzen 7 5800H processor, so my laptop can handle it. It was downsized in RC to 4k and 5m polygons, not even 39-40m, so not sure what is suddenly so demanding that UE5 has to crash within seconds of opening the Level. If it’s relevant to the issue, I only get one texture and one normal map in my export, whereas others’ workflows seem to have several of each.
