Posts disappeared after changing the post page permalink

Hi all,

I need urgent support for my blog infobynet.com .

This morning I was looking for page related errors in google search console and observed 404 for infobynet.com/home.
To fix this I edited the permalink of my home page (the page which was showing posts and was named as \blog earlier). I renamed it to home (thinking it will match the infobyne.com/home (big fool I was).

After this all post vanished from the blog except the most recent one.

Immediately I renamed the page permalink to again \blog, but still posts are not visible there.

Please help me fix this.

Regards
