RVT Broken from 4.25 to 4.26

I am having a problem with my RVT when I open my scene in in 4.26 (originally made in 4.25). The shader is now broken and not sampling my landscape. Does anyone know what has changed, why this is happening, and how to fix this issue? I noticed that in 4.26, there is also now a Virtual Texture Build section in the Details Tab, which was not present before. It had an exclamation point next to it, so I set it to ‘1’, which got rid of that but nothing happens. I also added a photo of my Shader, which you can see is now rendering black on the bottom of the shader ball, for reference. Not sure what happened when moving over to 4.26, as I changed nothing, and have tried adjust so many parameters in an attempt to fix it, with no avail. I’d like to add that I’m not very proficient with UE, obviously, and just trying to learn, so any help, guidance, or suggestions would be whole-heartedly appreciated. Thanks so much.

PS. I know there is stretching on the RVT, if anyone has any solution to this, would also be much appreciated. But that is for another issue all-together.
