Hello @상욱 백 , if cannot find Azure resources previously created with your user account you may have created them in another subscription or tenant. You can find all the tenants and susbcriptions your user belongs to in the Azure Portal. Try switching to every tenant and looking into each subscription to find your previously created resources. In the case you've removed yourself form the subscription and thus from being able to see its associated resources, provided you're Global Admin, you can Elevate access to manage all Azure subscriptions and management groups. As non admin you will have to requerst an actual Global Admin to restore your access to them.
