Awesome, thanks for the lightning fast fix, @andydotxyz ! I'll try to test it with the development branch, when I find some time.

I've now tested on the develop branch and don't see the problem anymore. Thanks again!

While searching for existing code that uses SetOnDropped, I found this: https://github.com/metal3d/fyne-streamer/blob/8800be35603ad89a6599e6a09152a988655e828a/examples/blender-peertube/main.go#L111

It looks like someone else already found the bug and also found a workaround. This works:

package main

import "fyne.io/fyne/v2"
import "fyne.io/fyne/v2/app"
import "fyne.io/fyne/v2/widget"

func main() {
	a := app.New()
	w := a.NewWindow("test")
	w.SetOnDropped(func(pos fyne.Position, uris []fyne.URI) {
		go func() { w.SetContent(widget.NewLabel("File dropped")) }()
	})
	w.ShowAndRun()
}

Fixed on Develop branch, but it probably missed v2.4.4 - if we do 2.4.5 before 2.5.0 then this should be in it
