Hi,
1. You can try executing the following commands:
restoredefaultpath
rehash toolboxcache
2. A corrupt installation may also be a cause of the issue.

Hi, I have the same problem but your solution unfortunately didn't resolve, instead a new warning appeared, "Warning: Function sim has the same name as a MATLAB builtin. We suggest you rename the function to avoid a potential name conflict." could you help me ?

Hi there!
Could you tell me how you solved your problem? I have the same issue at the moment, and can't manage to find a solution. Don't have access to Matlab either, so no way for me to run some commands in it.
Best,

Using the Command Prompt, you can navigate to your matlab installaton folder and launch Matlab without the desktop using
matlab -nodesktop
Then you can execute the commands from the Matlab command line interface. I am having the same problem as you, and folllowed this suggestion. However, Matlab will still not open.

I found similar error (NOT exactly same as the above error) on MATLAB 2022a, and resolved. On my situation, that error is because of existence of old version of MATLAB. After I deleted the old version, my new version of MATLAB worked.
