I got an e-mail from Focusrite this am and updated my 18i20 second gen as per instructions.  Wow, 3 BSOD so far, “Bad Pool Caller” x 1 and “Kernal Heap “ something x 2   Nothing in my config changed since the up grade. I currently have a ticket in with them, It happens when i open a CbB project then start the song.  I am up to date with everything (video, drivers etc), WhoCrashed indicates its focusriteusbaudio.sys that is the culprit.  Anybody else have such an issue ?
