Thank you very much!
I found my problem, was a "self-made thinking error"(threading and scope)

I use valaDevelop to debug valaDevelop, and i have an option "Break on
critical" ;-)

These are type checks for the GType system.

Probably text_view is null, so you may have some kind of scoping problem. You
are usingclosures that should encapsulate the enclosing scope.
One thing to try is compiling with debug information and then use
G_DEBUG=fatal-criticals and a debugger.
For example see
https://wiki.gnome.org/Projects/Vala/DeveloperDocumentation#Debugging
You are then in to checking versions of libraries on macOS and Windows and to
see if
they are up to date as possible or comparable with what was used on Linux.
You also need to be checking the version of Vala used and the C code generated
to make sure
there is nothing unusual.
Any idea ?
Nothing specific, but the above might give you some things to try.
// Timeout with 0 goes to "UI-Thread" ?! >
GLib.Timeout.add(0, () =>
The 0 specifies the delay before the timeout source is called, nothing to do with a
thread.GLib.Timeout.add() is a convenience method:
https://developer.gnome.org/glib/stable/glib-The-Main-Event-Loop.html#g-timeout-addIt
adds the timeout to the global GMainContext and the docs advise "the callback will
be invoked in whichever thread is running that maincontext"To specify the
GMainContext you would need to use https://valadoc.org/glib-2.0/GLib.TimeoutSource.html
and then attach() it to the relevantGMainContext.
