@hamza1MATADORES you did not say which sandbox this was? Is this happening to you on all sandbox or just one?

@hamza1MATADORES Have you checked that there is a reservation free, there is only 50 reservations permitted/capacity?

@bigevilbeard Yes , it is free and I can launch it to reserve it but after reservation process is terminating , I got the message that it's failed and the sandbox is active with errors , I tried several times but with no clue.

Looks like an issue with the spin up, the devnet team will need to look into this. I saw another thread today with the build problem.
