Hello, I have installed R2020a, and after that I have downloaded the update4 package, followed the instructions for the commandline (offline) update, performed the command in a dos-window and waited untill the update task disapeared in the task-manager.
After starting R2020a again, the red update-sign in the top-right of the matlab window was gone, indicating that there were no updates.
However, when selecting "Manage Add Ons" I get the message:
Dot indexing is not supported for variables of this type.
Error in matlab.internal.addons.AddOnsWindow/bringToFront (line 68)
Error in matlab.internal.addons.Manager/show (line 51)
Error in matlab.internal.addons.launchers.showManager (line 70)
the ver command also shows no update:

FYI, I will attempt to remove the license number from the inital post. It is not ideal to publish it to the world.

Your update is not installed. Should look like this:
>> ver matlab
MATLAB Version: (R2020a) Update 4
Click Help-> Check for Updates. Update 5 is available now. Maybe install it from there.

Do not use Add-Ons.
In R2020a, use: Help —> Check for Updates
