Crashing after downloading a model.

[justacalico]

What happened?

Linux arch 64bit, appimage, AMD GPU

after downloading a model it crashes

- While the app is crashed the stuff such as a UI and everything still works just the error message prevents me from doing really anything.

Exception Details

Exception

ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection. (Parameter 'index')

Pretty sure something like this would fix it. Because the when selection change event is being processed but between when the selection indices were determined and when the actual items are retrieved the source collection changed size.

Don't quote me on this tho as I don't usually use csharp.

// Instead of directly modifying:
Items.Remove(item);

// Do this:
await Dispatcher.UIThread.InvokeAsync(() => {
    Items.Remove(item);
});

```cs

After a little more debugging once the downloaded model 'raymond.safetensors' finished. As soon as it finished, Stability Matrix tried to Refresh list of models and then crashed.
