Product: PowerShell Universal
Version: 4.3.4

I messed up with just one line, but now no matter what I do the app won’t start again.
I wanted to take a look at a few themes.
The code below might or might not contain the mistake.
Basically I sent the wrong data to set-udtheme.
Now the app is broken.
Changing the code, restarting - nothing helps.

Edit:all you need to do is this:

$theme=get-udtheme -Name "xxx"
Set-UDTheme -theme $theme

It will show and error, then set the theme to null and the app is broken.
And that can’t be reversed (without some unknown trick)

Geeeze!
You can close this.

The error is “persistent” because of the browser cookies.
Whatever you change in the app does not get rid of the problem, until you delete all cookies.

That took me way too long :wink:
