OK. I’m currently able to run Frescobaldi 3.1.2 and lilypond 2.20.0 on Catalina on my iMac. Because of lockdown, I haven’t needed to do any lilypond work since March last year, and I don’t think I had to make any changes when upgrading from Mojave (32-bit compatible) to Catalina (64-bit only). Sorry I can’t help. Michael
