Simulink course not properly

Hi, I am trying to complete the Simulink Onramp course on my MacBook Pro. I am using the latest version of MATLAB R2022a.
However, the Simulink environment is extremely slow and buggy (although MATLAB works absolutely fine). I identified 3 problems:
  1. When I load the Simulink environment, only parts of it load. Sometimes the "Training-Tasks" bit on the left won't show up, sometimes the top part with the "simulation", "debug", etc. buttons won't even show up.
  2. Another problem I am facing is that some buttons don't work most of the times. I try clicking the submit button, but all it does it turn white. The "Training-Assessment" bit on the right shows that the signal was correct, but I can't move to the next assignment as if Simulink just crashed. I have attached a picture that shows this situation. In addition, sometimes clicking on the "debug", "modeling", etc. buttons on the top won't do anything.
  3. Another problem I am facing is that it takes Simulink about 5 seconds every time to load search results from the quick insert. Why does the quick insert take so much time to load?
I would like some advice on how to fix this issue. The problems 1-3 happen on the Onramp course, and problem 3 happens even in regular Simulink.
Thank you in advance.

Hi Nethesh,
It appears that the issues you're encountering are related to a corrupted installation and problems with graphics drivers. To address these concerns, I recommend the following troubleshooting steps:
  • To address potential graphics issues, start by launching MATLAB with software OpenGL. If Simulink works as intended, then it suggests that the root of the problem lies with the system's graphic drivers. Refer to the documentation https://www.mathworks.com/help/matlab/creating_plots/resolving-low-level-graphics-issues.html to learn about low level graphics issues
  • Conflicts or issues within your MATLAB path might be interfering with Simulink's loading process. To eliminate this possibility, reset your MATLAB path to its default settings using the restoredefaultpath function, followed by savepath to save the changes.
  • Simulink caches search results to speed up the quick insert feature. Clearing Simulink's cache might help. (Refer to the MATLAB Answer https://www.mathworks.com/matlabcentral/answers/1448564-can-t-delete-the-cache-folders-created-by-simulink?s_tid=srchtitle , to learn about clearing cache).
  • If the issues persist, they might be related to the user interface or other deeper installation problems. In such cases, a fresh reinstall of MATLAB could resolve the issues.
If none of the above solutions work,I highly recommend reaching out to MathWorks Technical Support for a more in-depth investigation into the issue.
