When I try to open my 2020a version of MATLAB, it quits immediately after displaying the startup window. What is going wrong, and how can I fix it? Thanks for any help.

Basically, when I double click the icon in my applications folder, the startup window appears for about a second and then vanishes. Nothing else happens. MATLAB isn't listed as an opened/active application, no other windows appear.

This appears to be a recurring issue with Accessibility Options as the root cause. It is possible that another application is using Accessibility features which are causing this issue.
You can refer to the following ML answer discussion and follow the steps provided by Jon Gotow in his answer to resolve the issue.
