I had the same issue where it would take me to the gaming services in Microsoft store after trying to launch Master Chief Collection. Uninstalling and reinstalling gaming services will not fix it. Follow the following which fixed my issue:

Click Start

Click on Settings (cog icon)

Click Apps

Click Halo Master Chief Collection

Click Advanced Options

Click Repair

Click Reset

This fixed my issue and hopefully will resolve yours also.
