Material Graph - Does not Display Texture Sample Black 2D Preview UE 5.6 - SUBSTRATE Material

When I switched in project settings to use Substrate materials and when I do drag and drop a bitmap 2D texture to the material graph, it showsdisplays black. Could someone give some pointers what to do in this case. Using 3080 Ti latest drivers. Dont think its my driver issue, maybe something in settings?

I just posted a fix here. It requires a source engine change - single line you can copy from my post and paste. Unreal submitted a fix in their ue5-main branch (which is their dev branch). Amazing this got missed in the 5.6 build.
