Hi roland abellano,
Based on the screenshot provided below, it appears that you're encountering challenges when trying to create a VM from the sandbox.
To address this issue, please follow the troubleshooting steps outlined below:
Step 1: Please sign out from all tabs in your current browser and clear the cache files. Then, try logging in again using your Learn ID credentials.
Step 2: Please sign out from your current browser session and try logging in again using an incognito window or private browsing mode.
Step 3: Please switch to a different browser and attempt to log in again.
Step 4: Please try logging in with a new personal Microsoft email account into the learning path using a completely different browser. If you do not have one, please create a new free Microsoft account. Note that you need to sign in with a Microsoft account, such as Office 365 or Outlook.com, for sandbox access.
Step 5: If you are still unable to create a resource due to insufficient permissions in the sandbox subscription, we recommend signing up for an Azure free account through the provided link https://azure.microsoft.com/en-us/free and creating a sandbox environment there.
Please refer to the link below for guidance on running Microsoft Learn training exercises in your own subscription:
