In the attached file, input Shift-M, 3/4, comma, period, and Enter. Dorico crashes for me. No idea if there are other scenarios that cause a related crash, but this is the second file I’ve gotten to crash using that input.
I stumbled on this intending to input 3/4,.5, but I omitted the 5.

Edit: ok, it crashes with other meters too. 6/8, comma, period, Enter does it.
