Cubase/Start Center Quit Unexpectedly (macOS Big Sur)

I updated to MacOS Big Sur version 11.2.2 and Cubase will no longer open, showing an “quit unexpectedly” error message. I removed all plugins and updated my eLicenser but no luck. I uninstalled Cubase to reinstall and while I got the same error message from the Start Center, I was able to go straight to the package and install it. Though it was successful, I am receiving the same message. I have no idea what to do from here; any help would be appreciated. Below are the Crashed Threads Report:
