S4S Error when uploading normal map

     Hello I'm trying to upload my normal and roughness map to my item but I keep getting a pop up window whenever I try a dds or png file or it will upload but I can't save and it will crash. I'm creating a door and I need my normal map to create the depth for the panels. but I'm having trouble. The item works normally in game as it should. I just can't get my maps to save...
