Unable to export downloaded 3d assets to other software

Setup quixel bridge a while ago and im able to export textures to other software like cinema 4d and blender, both old downloaded ones and new ones from fab but when it comes to 3d assets, it refuses to export the models and gives no errors. the assets i have downloaded a while back on my computer get imported just fine but with the new ones im downloading from fab, quixel megascans mainly, they wont export. anyone else having this issue?
