Cubase 10.5 Crashes switching to UR44

I purchased and just installed Cubase 10.5.11. It crashes when I switch to the UR44 – which works fine in Ableton, Live, Logic, etc. I figured if it worked with anything, it would be a Steinburg DAW (?!). Here are the details:

UR44: Latest Driver Yamaha Driver (2.0.2), Latest Firmware. I believe it’s the first hardware revision.
Cubase: 10.5.11 / Downloaded today.
MacOS: Mohave 10.14.6

I’m trying to transition to Cubase and move away from Mac, but Steinburg is not making it easy :frowning: . UR44 has been solid for years.
