No visualization of Mechanics Explorer when starting Simulink from GUI

Hello,

I guess the title already says it all.

I built a simmechanics multibody model of a robot in Simulink which is visualized when starting the Simulation directly from Simulink.

But when I try starting the simulation from a GUI (Matlab App-Designer) with the command:

%%Start Simulation
simOut = sim('Modell_Roboter_Tisch_InverseKin.slx','ReturnWorkspaceOutputs','on');
assignin('base', 'simOut', simOut) %Writes simulation output to base workspace 

there is no visualization of the robot. The Mechanics Explorer windows just stays grey:

I already tried zooming out/in, enabling all components, etc.

Hope you guys can help me with this problem.

Thanks in advance!

Did you manage to solved it somehow?

Unfortunately I didn't find a solution.

From the one day to another it just worked again as before... But I still don't know what the problem was - sorry.

Same problem here. Could someone help?

Did you solved?

I have the same problem. For me, the workaround is to have the model file (.slx) open in the background. The problem appeared when I updated to Matlab 2020b. I hope this bug is fixed in the next update.
