{UE 5.0.1} Metahuman consistant crashes when I switch to lit mode.

I use blender to modified the metahuman shapes and transfer back to UE5 via mesh morpher, everything works fine and great. Then I use Substance painter to modify the head and body textures, also the 3 wrinkle base color / normal maps (total 6 maps) plus 2 emission maps, i sucessfully plug all maps, but when I switch from unlit mode to lit mode to see the outcome, my GPU usage ran up to 90%+ immediately and after few seconds, it crashes. I tried DX 11 / 12. edit TDR delay values, reboot / restart computer many times, it still crashes.

Need some advise here please.
