i have xbox game pass but can't download games

To be absolutely sure, I'd leave it set to default unless you absolutely need to change it around. You can change it to another location, but honestly, it seems like some games from the PC Game Pass app simply don't like being installed on external drives or in external locations. If you go into the Xbox PC app, click on your portrait in the top left, then go to settings, and then general, you should be able to select a default location where games save.

Check that your Xbox games are installed on the correct drive.

Type 'Storage Settings' into the Start Menu and open the associated setting to check if you have enough device storage available. The Xbox app should warn you if you've run out of space, but sometimes it may not.

Check that your storage device isn't full.If Microsoft itself is having issues, that may also cause broken downloads. Check that the Xbox network isn't down.Check your speed on, and ensure you're not connected to a VPN or something like that. I know it seems simple, but sometimes a download may stall if your internet is too slow or suffering from some kind of interference, even if the rest of your web seems to be working. Check that your internet is properly connected.Here's how to check your Windows device limit. Sometimes the Microsoft Store doesn't warn you that you've exceeded your device limit, which may incur problems when trying to download things that require a license. If you have a bunch of old devices you've connected to that you no longer use, you should remove them. The Microsoft Store only allows you to access up to 10 devices at a time with your Microsoft Account. Check that you didn't hit your Windows device limit.
