Hi Barry,

In order to work around the issue, start MATLAB with 'nojvm' tag. Please follow the steps given below:

1. Open Command Prompt and navigate to the drive where you installed MATLAB.

2. Execute the following command to open MATLAB with 'nojvm' tag in Command Prompt:

>>matlab -nojvm

3. MATLAB Command Window will open up and then you can execute the following commands in it:

>>restoredefaultpath
>>rehash toolboxcache

4. Restart MATLAB normally.

Hope this helps !
