QtDragon GUI QTvcp ERROR! Message # 1

Hi, I have a problem with qtdragon.
I have linux 2.9 master and tried to install qtdragon_hd.
However, I get an error just like in the picture.
What am I doing wrong?
 

Looks like you are using master not 2.9.
Can you run linuxcnc in a terminal and post any output?
posting your config files might be helpful too please.

I installed 2.8.4 buster from iso. Later I upgraded to master. ( my mistake i took the example from the 2.9 update video )
then I installed Python 3.7, Qt 5 and then Install QtPyVCP. I had to manually install pip3 numpy because some error popped up.
When I open via CNC-LinuxCNC-sim.qtdragon_hd then it starts. One when I created the configuration via Stepconf and rewrote all the data as in the example:
linuxcnc.org/docs/devel/html/gui/qtdragon.html
this pops up the error seen in the first post.

Can you tell me how to post any output to you?
If I type linuxcnc in the terminal, this is what I get:
 

You can just copy and paste the output into the forum.

Did you mean this?

 

ok ya that shows a hint.
If I understand correctly, it's a configuration that you have editted that does not run properly?

Now I need to see your configuration files. Archive them and post them here please.
