it is suggesting that those actions, are not found. the error occurs because, aside from the obvious, someone has a project setup to use them. they are core actions, so there is no plausible reason for them to be missing.
I have done a fuzzy search in this forum but fail to get any hint on recovery actions. Is that some sort of plugins that has gone missing? I have also renamed the current
kanboard and unzip a new one in, the issues persist…

I have compared them with the versions in your post.
There is no difference on TaskAssignSpecificUser.php, but some differences on
TaskEmail.php:
