I found the culprit : ListView.
It crashes if the component you want to remove include a listview
You can see it on https://bitbucket.org/WillNa/haxeui-bugs/, bug 2 and 8
(for HXCPP debug, I tried hard for 2hours without success…currently looking for more details on vscode .json file, I don’t understand how task and launch works together)
