Game Pass showing () unknown available

This isn't just for Forza this is for every game.

I've been having this exact same issue, and I know for a fact it isnt my drive. Not even able to download games like Doom 64 which is like 60mbs. However I'm able to download games I've bought and own, just for some reason anything gamepass isn't working despite the fact I have ultimate. I've seen others with this issue and there's been 0 solutions. I tried talking to online support and they said they've been getting several reports and they're working on it.

There may be a problem with the disk. i think try this

or the game may have been uninstalled

That game is available with Game Pass for PC which is included in Game Pass Ultimate. So it should be free. Is that the only game not showing as available?
