SDL Studio 2021 Seems to have Disappeared and Will not Open post-installation of SP2

I opened SDL 2021 and installed SP2, as well as updating some other apps from the APP store - 16.2.10.9305

Now I am completely unable to open the app. I double click on it and then it looks like it will open, but disappears. I see Studio 2021 in my program list but there is no option to repair the installation. I have attempted to reinstall several times, but to no avail.
