Bug: Hot Reload and Uno Platform Studio crash when invoked from Elapsed

[Lamparter]

Description

It appears that Uno's hot reload and Studio features crash when invoked from the current version of Elapsed.
They are automatically invoked here:

https://github.com/Lamparter/Elapsed/blob/f6b86c5fc4a3dc7b217d2605a77f0dd619cbf638/src/app/Riverside.Elapsed.App/App.xaml.cs#L93-L95

However, they seem to crash on start-up (the app still runs, but without hot reload or hot design).

Steps to reproduce

1. Run the app in preview configuration
2. See the error in console with Hot Reload and Uno Platform Studio
3. See the status indicator error

Comments

I have managed to trace back this error to the changes introduced in this commit: c28d7d1

It looks like a potential workaround is to rename the Preview configuration to Debug.
However, that doesn't fix the issue, especially considering the app's entire build system and CD integration are built around the configuration being called Preview.
