Error when importing GLB scenes via Admin Panel and opening them in Spoke as new projects

[redp1ll]

Describe the bug
When a GLB scene is imported via the Admin Panel and subsequently selected as a new project in Spoke, an error occurs. This error happens because GLB scenes, when imported in this way, aren't supported as editable projects in Spoke. This can be misleading to users who attempt to remix these scenes and encounter an error without a clear explanation.

To Reproduce
Steps to reproduce the behavior:

1. Import a GLB scene using a scene link via the Admin Panel.
2. Go to Spoke and select "New Project."
3. Attempt to open the imported GLB scene as a project.
4. Observe the error that appears.

Expected behavior
Either:
GLB scenes imported via the Admin Panel should not appear in the "New Project" selection screen in Spoke if they cannot be remixed.
Or:
A clearer error message should appear, explaining that GLB scenes imported through the Admin Panel cannot be opened as editable projects.
