why cant I download a game I own on Xbox to my pc

Because they are two seperate games as far as the system is concerned. Relatively few titles grant you both versions.

Games have to support Play Anywhere in order to download on both the Xbox and PC without having to purchase twice. Not all games are available that way. https://www.xbox.com/games/xbox-play-anywhere

It depends on the game, if the game is capable of offline gaming you can definitely just click "offline permission" on your Microsoft Store App. Then try to play any of your games.

Just a friendly reminder though that we can play Xbox games both on Xbox and PC if the game is an Xbox Play Anywhere game.

when I view Red Dead Redemption 2 in Microsoft store, which I own on my Xbox one s, I tried downloading the game because I already own it on Xbox, but when I try to download it on Microsoft Store it always says “this product can’t be installed on this PC” I have been struggling for at least TWO days, do I have to wait until it’s available on the Store or is it just not available?

Red dead redemption 2 isnt a play anywhere title so if you want to play it on PC you'd have to buy it for PC. Having the Xbox copy wouldn't give you a PC copy.
