I think ur issue comes from the M365‑join dropping elevation before SQL wakes, so a single login with real local‑admin to bring the SQL svc up is the cleanest fix… and giving PowerBI read/exec on the share early avoids the next stall.
How deploy copilot using Vscode when running PowerBI backend?

When hosting SQL Server 2022 on M365 Office instance, the boot screen doesn’t allow administrator access for Power BI backend.
- Run SSMS as Administrator: Right-click SQL Server Management Studio and choose Run as Administrator to get full access.
- Check Permissions: Ensure your SQL login has sysadmin rights. In SSMS, go to Security > Logins and verify that the correct account has sysadmin role enabled.
- Power BI Access: Make sure the Power BI service has the right permissions to connect to your SQL Server. Use either Windows or SQL Authentication depending on your setup.
- Network/Firewall: Double-check that no firewall rules are blocking the connection between Power BI and SQL Server.
If this doesn’t fix it, take a look at the error logs in both Power BI and SQL Server for more clues.
Hope that helps. Let me know if you need further details.
Thanks,
Akhil.
