Thanks for the clear reproduction. I was able to reproduce this and it’s now fixed in the next release: https://feedback.objo.dev/bug/670

The underlying issue was that Slider is backed by Avalonia’s range control, which requires:

Minimum <= Value <= Maximum

Studio could save a layout with Value = 100, Minimum = 102, and the default Maximum = 100. When the app ran, those values were applied separately and Avalonia threw an unhandled exception.

The fix is now in place:

Slider and ProgressBar now coerce range values safely at runtime.
Studio normalises invalid range values when loading/deserialising layouts.
The inspector now updates Value, Minimum, and Maximum together after a range edit, so it won’t display an inconsistent state.

So if you set Minimum above the current Value/Maximum, Studio will bring the range back into a valid state rather than letting the app crash.
