My problem with getting error code 0x803f800e "Looks like you need to renew your Xbox Game Pass" has gone away and we've been able to start Minecraft without issue. Looks like MS or Mojang fixed something on their end.
I'm seeing this exact same issue. I had ordered the Minecraft Master Collection back in 2019.
Hi SAM197706, I was unable to find the Minecraft Master Collection in the store, which was the version I bought. I too had uninstalled Minecraft and couldn't find that collection in the store. I found the order in my list of orders on my Microsoft account and from there I was able to go the Minecraft Master Collection store page and initiate an install to my XBox. This might work for you if you haven't found a way to reinstall Minecraft.
