Ionic Cordova phonegap-plugin-push did work on IOS but stopped recently with 'kill() returned unexpected error 1'

Question

I have added phonegap-plugin-push plugin to an ionic 4.10.2 about two months ago, it worked and I left the project alone for a while, now when I recompile it (I don't have the working version anymore) it doesn't work.

The only notable difference since then is the console messages:

kill() returned unexpected error 1

as I have read they have to do with WKWebview and it was never been fixed,

but no one have ever mentioned it has anything to do with push notifications

I also get PushPlugin skip badge

I don't see any version changes in package.json that could indicate a change in versions of plugins.

nothing have change with Firebase and Provisioning files either.

any ideas? did it happen to anyone else recently? or is it just a coincidence and I should put more effort in searching the problem elsewhere
