Cubase pro 14 spinning ball freeze

I’ve been trying to use Cubase Pro 14 with my Steinberg audio interface on a 24-inch iMac M1 (macOS Monterey). I’ve been using the built-in audio at times, but when I connect the Steinberg interface, Cubase freezes with a spinning ball. I tried reinstalling the Steinberg Download Assistant, switching profiles, and adjusting audio preferences, but no luck. Also, system preferences crash when I change sound settings. What else can I do?
