Hello @조휘성 (유도경기지도학과)
You would need to work with the Global Administrator of your tenant and he can run Enable-MsolDevice -DeviceId "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx" -Force
cmdlet to enable your primary computer. Where "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx" is your device id. Unfortunately, we don't have permission to perform this operation in your tenant.
