There is definitely a bug in Studio One. Any time you try to click on a numerical value to change it within a plug in and change position of the cursor using the arrow or delete key(s) Studio One will just shut down instantly. It happens with all 3rd party plugins nearly 100% of the time. It's happened to me with Waves and Izotope plugins. I'm using a MAC / Catalina. Newest version of S1. This happens time and time again. I report it to Apple every time. I always use AU plugins because VST is unstable half the time anyhow.
