Yep! They figured it out for me. I deleted my preferences in Photoshop and it worked. When opening Photoshop, I held down Ctrl+Alt+Shift, and it prompted me to delete my preferences. I restarted Photoshop, ran Quixel, and all the proper maps in the Export Target area created successfully!
I suddenly have the same problem. I deleted the preferences and restarted but it didn't work. I even upgrade and downgraded to a different Photoshop version. It didn't work.
