Active php session was detected

This ^^^

I get the same error, along with the REST API one, both under Site Health. It also gravely slows down my Admin areas.

I did a manual and temporary fix, as per forums, by editing file “flat-shipping-rate-by-city.php” at line 221 from this:

    session_start();

and changing it to this:

session_start( [
        'read_and_close' => true,
    ] );

I can confirm it fixes both errors and the admin loading speeds.
