This is one of the reasons I don’t use GamePass, because it all goes through the crappy Microsoft Store which always gives me weird download errors, and when trying to research the issue it just leads to nothing that works.
God forbid you reinstall Windows and have your GamePass games on another drive. It won’t let you re-use that partition because the games folder is “owned by someone else” even when you’re signed into the same Microsoft account, and it won’t let you delete it because its protected by Windows… You either have to nuke the whole partition, delete it from Linux, or go through the whole take-ownership ritual which is buggy at best.
Thankfully Minecraft Dungeons does work via Proton, though I’m not super familiar with macOS so I’m not sure if Proton works for macOS given that Apple’s platforms use Metal rather than Vulkan (though I hear a translation layer is being worked on for Vulkan->Metal).
