Sea of Thieves disappeared from my game library ?

I no longer have Steam on my computer and I got a refund for Sea of Thieves from Steam so it's not even in my Library. I also uninstalled the Steam version of Sea of Thieves from my computer.

Until this day I didn't know why sea of thieves and state of decay 2 would be gone from my library, thanks for this info.

I did as you said reinstalled gaming services and then i went to the sea of thieves tab and it crashed again so no result.

Also sea of theives appears "ready to download" in my library but when i click on it nothing happens.

After uninstalling and reinstalling Sea of Thieves and the Xbox Game Bar many times, I am able to invite and accept invites on Sea of Thieves Insider through the Game Bar. I am able to send invites from the Game Bar for Sea of Thieves. However, when I receive an invite or try to join in on Sea of Thieves, I still have the same problem. Sea of Thieves and Sea of Thieves Insider are two different builds. There must be a file somewhere on my computer that is not being deleted or uninstalled and it's not allowing me to accept these invites on just Sea of Thieves. I don't know how to find this file.
