Errors with Nightly Build

Hi. Sorry for posting in English, but you know the status of English community :)

I've already posted on github but I think that the feedback will be here much faster.

I have installed Nightly Build (zip) version from official avisota.org website. I did not use composer, on Windows it does not work.

Now if I want to setup avisota (click on Message, Recipient, Settings -> mailing list, etc.) I get bunch of errors in back-end, usually there is the same error (attachment).

Is there any dependency that is missing or some other solution for fixing this issue?

Thanks.
