Hi @Quan PHAM,
Thanks for reaching out to us. We are very pleased to support you.

Not set as home page, just opens the page:
When set as home page:
Since we can't reproduce your situation, we need to narrow down the problem and try some things.
- Please check again that your sites that are having problems are correctly setting the page as the home page.
- Make sure you have Edit and above permission for these sites, otherwise you won't be able to create lists or file libraries and naturally these options won't appear.
- Is it possible that other users with sufficient permissions accessing the same site can also reproduce the issue? If it doesn't, it is probably a cache issue, so please try clearing your cache and checking again.
- Is the problem still occurring if the site in question has a new custom page set as the home page? It is very likely that the original site page is broken and causing the problem.
- Please create a new site and assign a new homepage to see if the problem persists. It is likely that the original site is corrupt and causing the problem.
If you have any questions, please do not hesitate to contact me.
