Describe the bug

The last recent PRs didn't had working preview Playgrounds.

1. The first reason was easy found and fixed fast: I needed to update a GitHub token, that I renewed meanwhile. ✔️
2. Now things got strange:
   1. The normal preview link like this, fails
   2. It still shows, that the zip file is loaded from the artifact and installed
   3. But it won't activate automatically
   4. Even I can do that manually without any problems
