While giving an assessment for copilot studio, I was required to open the copilot studio portal in the VM. after trying multiple time's it keeps loading. even tried different browsers and incognito mode. I have also reset the site permissions/provided all and cleared the cookies and related data. but still it just keeps loading.

    After creating a trial in Copilot Studio, the app may hang on an infinite loading screen.

    By default, it redirects to a “Default” environment:

    https://copilotstudio.microsoft.com/environments/Default-{id}/home

    In some cases, this environment isn't fully provisioned or not linked to a working Microsoft Dataverse instance, so the app fails to initialize.

    Solution

    Replace the environment ID in the URL with a valid Dataverse environment (e.g. from your Microsoft Power Apps developer environment):

    https://copilotstudio.microsoft.com/environments/{env-id}/home

    The answer above pointed me in the right direction. Had to still do some research so I want to help the next person. Here is the solution:

    Problem

    After signing up for a Copilot Studio trial, the app hangs on an infinite loading screen. By default it redirects to a URL like:

    https://copilotstudio.microsoft.com/environments/Default-{env-id}/home

    This points at the tenant's Default environment, which often has no Dataverse instance attached. Copilot Studio requires Dataverse to initialize, so it never finishes loading.

    Solution:
    Create a new environment that has Dataverse enabled, then load Copilot Studio against that environment's ID instead of the Default one.
    Check your Default environment

    Go to Power Platform Admin Center → https://admin.powerplatform.microsoft.com → Environments → click your Default environment.

    Look at the Dataverse column / Click + Add Dataverse on the Default environment page, fill out the form and save it. This should generate an environment apart from the default one. Now, get this new environment ID (it should not start with "Default") and replace it in the URL https://copilotstudio.microsoft.com/environments/{env-id}/home. Where env-id is the new one generated.

    This is the solution that worked for me.

    The behavior matches a browser-side loading issue similar to other Copilot/Studio experiences that depend on cookies and site data. Use the following targeted checks and fixes inside the VM where the assessment runs:

    1. Allow cookies and third‑party cookies
      • In Edge: Settings → Cookies and site permissions → Manage and delete cookies and site data → ensure Block third‑party cookies is Off.
      • In Chrome: Settings → Privacy and security → ensure Allow third‑party cookies is selected.
      • In Firefox: Settings → Privacy & Security → under Enhanced Tracking Protection, select Custom and make sure Cookies is unchecked.
      • In Safari (if applicable in the VM): Safari → Settings → Privacy → ensure Prevent cross‑site tracking is unchecked; Advanced → ensure Block all cookies is unchecked.
    2. Re‑clear cache and cookies specifically for Microsoft domains
      • Clear cookies and cached data for microsoft.com and any Copilot Studio–related URLs from within the VM browser.
      • Close all browser windows in the VM, reopen, and try the Copilot Studio page again.
    3. Check for blocked pop‑ups and site permissions
      • When the page is “stuck loading,” look at the address bar for blocked pop‑up or cookie icons.
      • Explicitly allow pop‑ups and cookies for the Copilot Studio site in the browser’s site settings.
    4. Try a clean session in the VM
      • Open a new InPrivate/Incognito window after applying the cookie/third‑party cookie changes and then navigate to the Copilot Studio URL.
    5. If still stuck loading
      • Because this is running in an assessment VM, there may be network or policy restrictions in that environment. If the above steps do not resolve the issue, report it to the assessment or lab administrator so they can verify that required Microsoft and Copilot Studio endpoints are not being blocked and that the VM image is correctly configured.
