Hello,

After install a new version of npm proposed with sudo apt-get install && upgrade my magicmirror screen is black…the pm2 logs shows ;

magicmirror@2.9.0 start /home/pi/MagicMirror
sh run-start.sh

Starting MagicMirror: v2.9.0
Loading config …
Loading module helpers …
No helper found for module: MMM-EmbedYoutube.

Whoops! There was an uncaught exception…
MagicMirror will not quit, but it might be a good idea to check why this happened. Maybe no internet connection?
If you think this really is an issue, please open an issue on GitHub: https://github.com/MichMich/MagicMirror/issues
Launching application.

pm2 start or stop are ok…but always black screen after sudo reboot…before to restart with a new sd card have you an idea ? Thanks
