I’m also experiencing this issue, did you ever find a solution?

i have the same problem

I figured out the issue on another thread

My C:\Users\USER\ .ionic\ionic.config had been corrupted and deleting it solved the issue

if that’s not the issue then navigate to where you have ionic installed, for me it’s
C:\Users\USER\AppData\Roaming\npm\node_modules\ionic\lib\ionic

then open a command prompt and run "npm install -g node-debug
after installing run “node-debug app.js” from that folder and step through the program to identify the error
