Menu bar missing in Simulink

I installed an academic licanse of MATLAB R2016b and Simulink on my new computer a couple of days ago and started working on a simulink project and everything was going fine. However when I opened the simulink model today the toolbar was missing. See figure.

I have tried rebooting matlab and my system (windows 10 64-bit) which did not help, as well as googling the issue, but have not found any conclusive answers. If anyone knows how to fix this problem it would be much appriciated.

Best Regards

2. Run the following command to rebuild Simulink and Library menus and toolbars:

3. Close all the instance of MATLAB and then restart.

Double check which button are you choosing. Blank model with the Run button, blank library have no that button.

That doesn't work for me in 2019b. Fixed only for a little amount of time. Are there any permanent solutions?
