Error icon in the thumbnail view

hi there. Recently, I noticed that GTV is spitting out an error when trying to display the thumbnails. I hope this screenshot can help give info. This particular texture was made with Substance Designer. My textures are stored on shared network drive. The only way to resolve this is by previewing the texture (double click), in windows. I guess at that point it's creating thumbnail data somewhere. After doing this, it works in GTV.

Is there a way to resolve this without always having to preview the texture first?

Cheers!
