ExB 1.9 Dev is broken? Strange errors out of no where when downloading an app package

[ScottHiggins_PVGIS]

Not sure if anyone else is experiencing issues out of nowhere with their 1.9 Dev Experience Builder environments. But two of us are having the same issue in separate environments.

Friday afternoon, I was able to export/download Application packages to put into our hosting environment. I have updated nothing and didnt touch it since the last successful download Friday afternoon 3pm.

Exporting a new edited today, I invariable get "Not found" error or 

And my Server command throws weird errors:

I dont even know why. One our our technicians, separate environment (local 1.9 dev) gets the same error when exporting, or a variation:

So obviously something major is going on with the dev environment. This is putting us seriously behind on our development cycle when we cant even export versions into our test host environment. He exported a version this morning no problem.

Could someone please help, explain what the heck has changed with the stuff, or better yet fix your stuff. This getting to be unreliable as an application development environment. Sigh, ESRI.

Well, still broken today for two of us. It seems to be populating icons and something to do with calcite components, which isnt even referenced or used in apps:

@ScottHiggins_PVGIS  I am getting the same issue today (9/8/22). Strange as I have downloaded a few apps from 1.9 last month. Have you opened a ticket with Tech Support?

@RobertScheitlin__GISP -

Did you find a fix for this? I've run into the same issue. Thanks.

[RobertScheitlin__GISP]

Nope. I never got past this.

Dang. I've done clean installs of Node and ExP, and keep running into the same issue. Have an open case with Esri and trying to work through the issue. Will report back if I learn anything.

@ScottHiggins_PVGIS  We have Esri support ticket open but not much progress.  I am trying to narrow down the possible cause:

• Which OS do you use?  I am on Windows 10 and not experiencing the issue, while another developer in our organization is on Windows 11 and experiencing this issue.
• Do you happen to use `@arcgis/core` module in your custom development?
• Do you happen to have a folder named "tests" anywhere in the custom widget(s) you wrote?

@kim_hspartner - could you please let us know Esri support ticket number you opened?

This started happening to me last week too! I've tried reinstalling Node, ExP Developer, and rolling back to a previous build  with no success.
