Mix error "UnhandledPromiseRejection"

[TheFreeman]

Hi,

i have installed laravel-mix-favicon verion 0.3.4
until now, it works fine on every "npm run *" :-)
But until today, there is an unexplainable error from node:

When i comment out the ".favicon"-part in webpack.mix.js, everything is mixing fine.
Any ideas?

Thank you in advance.
LG
