CI 4.1.8 session issues

Hi guys,
I have weird issue with CI4 session.

Every 2nd page reload throws ErrorException - session_start(): Failed to decode session object. Session has been destroyed

- i did upgrade to CI 4.1.8
- i use Myth:auth, but even if just refresh homepage without login
- if i login, i land in dashboard - OK, F5 and session is gone

Config/App.php

PHP Code:

public $sessionDriver = 'CodeIgniter\Session\Handlers\DatabaseHandler';
public $sessionCookieName = 'ci_session';
public $sessionExpiration = 0;
public $sessionSavePath = 'ci_sessions';
public $sessionMatchIP = false;
public $sessionTimeToUpdate = 300;
public $sessionRegenerateDestroy = false; 


Created MySQL 'ci_sessions' table from userguide:

https://codeigniter4.github.io/userguide/libraries/sessions.html

Code:

CREATE TABLE IF NOT EXISTS `ci_sessions` (
    `id` varchar(128) NOT null,
    `ip_address` varchar(45) NOT null,
    `timestamp` timestamp DEFAULT CURRENT_TIMESTAMP NOT null,
    `data` blob NOT null,
    KEY `ci_sessions_timestamp` (`timestamp`)
);

ALTER TABLE ci_sessions ADD PRIMARY KEY (id);

PHP 7.4.27 php.ini

Code:

session.auto_start Off Off

session.use_cookies 1 1
session.use_only_cookies 1 1
session.use_strict_mode 0 0
session.use_trans_sid 0 0

This session setup always has worked. 

Can anyone tell what config options i need to change? Server variables?
Maybe some hidden stuff in Myth:auth module?
What setup does work for you?
