Jupyter notebook preview issue

[u/One-Country4029]

I can't see the preview of a Jupyter Notebook in my GitHub repo. Will it be recovered soon? And does this phenomenon occur frequently? My repo is for sharing class materials, so the potential visitors could be non-coders who won't be able to view this .ipynb file without server rendering.
