Admin Auto Logout after few minutes unexpectedly

I am using wordpress latest 5.9.3 version.

When I login to admin, after 25-30 minutes, I get auto logout from admin section and losing everything creating during that time.

I installed and tried various plugins for increasing auto logout time.

Changed timing in Idle User Logout, Disabled it for wp-admin….

Cleared cookies in browser too…

Also tried adding following code to functions.php file. But unfortunately, nothing helped me…

function logged_in( $expirein ) {
   return 604800; // 1 week in seconds
}
add_filter( 'auth_cookie_expiration', 'logged_in' );
