How to limit post (Exception pages) for current user in each role in front end?

Thank you for reading this question

I need an option or code for each user in each role to see only their posts at the front end, and other users' posts to be completely hidden from them, even in search results (without any messages or effects).

More details:

The user has to log in to receive the content, and when they log in, they only sees their posts (as if there are no other posts on the website).

I need all pages to be excluded (show for all). Only hide other users' posts

Any help would be appreciated
