Ionic Serve on fresh ionic 4 project does not work - please help


#1

Today i wanted to show a client some progress on a app i am writing.
I started -> ionic serve as usual but it stopped with this messag after a quick wait:

ng run app:serve --host=0.0.0.0 --port=8100
[ng] angular-cli[7128]: src\node_contextify.cc:627: Assertion `args[1]->IsString()’ failed.
[ng] 1: 00007FF676F821C5

[ng] 8: 00007FF67738A75B
[ng] 9: 000000EBF00D0361

[ERROR] ng has unexpectedly closed (exit code 134).

    The Ionic CLI will exit. Please check any output above for error
    details.

I started a fresh ionic 4 project to test if something was wrong with my project… same result.
I uninstalled and reinstalled ionic via npm. No change.
I reinstalled node.js -> no result.

Can anybody point me in the right direction please?
