Can't upload files to Substance Painter

Hello Friends, I originally purchased Substance Painter on Steam but noticed that I couldn't upload any files so I purchased a license from Adobe. I go to File> Import Resources> Add Resources> Click on a file and it won't upload. I've also tried Dragging and Dropping but it won't load. I've used Substance Painter before and never had this issue. I've tried multiple files including obj and fbx. Same result. I'm not doing anything extraordinary like UDIM's. All very simple files with the UV's properly layed out in Maya. Please help.

Also, I've removed and re-uploaded Substance Painter three times with the same result. I can open tutorials that have sbsar files. I'm on Windows 11 running a GeForce 3080.

Thanks much
