I just installed 2020a and I have the problem that I get all kinds of error messages such as:
Unrecognized function or variable 'matlab.internal.addons.updates.getSupportPackageUpdates'.
I notice that a similar problem was posted concerning 2019. The solution given is to type the commands:
restoredefaultpath
rehash toolboxcache
savepat
This seems to work, but not permanently. Is there a more permanent fix?

Hey Fred,
Have a look at these other MATLAB Answers posted on the community:
There seem to be a few other workarounds to solving this issue apart from the three commands that you've mentioned.
Also, please try to perform a complete reinstallation of MATLAB in case the issue persists.
Hope this helps!
