Thank you for reaching out to Microsoft Flight Simulator Support today.
We have been receiving reports from other users having this 2047 error message, our team is researching the root cause in this moment and could be triggered by congestion in the servers, in the meantime just try again later and if the issue persists try the steps listed below as many of our users were able to get back into the sim by performing this troubleshoot.
To start, try these steps (in this exact order) suggested by a MSFS forum member and see if they help:
1. Open Xbox app and sign out.
2. Then, open Microsoft Store app and sign out.
3. Go to Windows Settings → Apps → Installed Apps, click the three dots next to Gaming Services, and select Uninstall.
4. Restart PC.
5. Open Microsoft Store app and sign in.
6. Then open Xbox app and observe the progress from 0% to 100% - this is when Gaming Services is being installed.
7. Finally, sign in to Xbox app and launch MSFS.
