i was installing Mm2 today and tried out some modules.
All was working fine (except Octoprint Stream) and then from one minute to the other all modules were hidden or not shown on the screen except the clock with date

Here you can see my config.js (also resetted again and after putting in a new module same error as above)
What am i doing wrong or where is the mistake?

also if i start “npm install” then a lot of errors appear
