I have tried to install games in the Xbox app for the first time since update to W11, and I am facing issues regarding drives installed in my system. I originally opened a question on the user troubleshoot forum regarding the matter, I have been replied with several things to try, none of them actually worked in the end.
It might be an issue related to W11, hence the message here.
Hope someone can help or figure out what's causing the issue, here is a link to said post with all the steps I have taken to try and fix the issue.
Actually you could have posted your question on the Windows Insider forum in the Microsoft Answers which is: https://answers.microsoft.com/en-us/insider/forum Try visit your device's manufacturer website and download and install all available drivers. Run Windows Update and download and install all updates. Make sure report this issue using the Feedback Hub app.
