But don’t you get the error when click on button “Start”?

Beatrix_Willius · November 19, 2017, 1:23pm

How did you make the crash? This gives a ThreadAccessingUIException on

WebDett.LoadURL (c.sUrl)

Tim_Parnell · November 19, 2017, 4:20pm

You did cut off the call stack. The important part are the first lines from top to bottom which carry the name of your application. So somewhere after 54 com.apple.JavaScriptCore it will say something like nnn fornext.debug … . These are the interesting parts from your application where the crash starts.
