[Exception] Cannot apply patch 2869592 - Disabled update module shouldn't produce a status report warning (https://www.drupal.org/files/issues/2020-02-07/2869592-remove-update-warning-34.patch)!

That patch no longer applies on your version of Drupal Core. It looks like you will need to reroll the patch to apply to the Core release that you are trying to upgrade to.
