All my Spaces stuck in Building with empty logs

I fixed the issue on my Space.

It turned out to be a Gradio version conflict. Spaces was installing gradio==6.9.0 because of sdk_version in README.md, while I also had another Gradio version in requirements.txt.

The fix was simple:

• remove gradio from requirements.txt

• keep the version only in README.md

After that I ran a Factory Reboot to clear the cache, and the Space built successfully.
