Content Browser Issues

Over the past few days I have lost all of my Quixel assets that used to be in the Dash content browser under the Quixel tab. For whatever reason only the past 5 decals I've downloaded are showing up when on the Quixel (old) tab. I've checked the paths in the prefs and they are correct like they've always been. I've also tried using the FAB tab in the content browser. I've added an asset to my project from FAB and nothing ever updates in the content browser in the FAB tab. However, all the PolyHaven stuff shows up like it always has, no issues. I've clicked on the little cloud and circle arrow update things at the top as well (see attached image) to try and update the browser, but they don't seem to do anything and always say 0% no matter how long I wait. Any help here would be appreciated! Thanks!
