I found a post here that describes a similar problem, but nothing there fixed my “problem”
https://forum.magicmirror.builders/topic/19305/rookie-question-builder-encountered-a-problem-see-magicmirror-messages-for-info

there it looks like “@sdetweil” fixed the problem.

and i found nothing MMM-Config releated in the log Files.

on npm run config:check

magicmirror@2.30.0 config:check
node js/check_config.js
