Same here... am trying with a 4 minute high quality voice sample using the 'Faster' analysis option, but after a few hours left to its own devices it's still stuck at zero. But this is with Resolve Studio v20 beta 2 build 27 running on a vanilla 2020 M1 MBP under macOS Ventura 13.6.7 ... I note that the v20 minimum requirements state macOS 14 Sonama or later, so that might well be the problem on my end.
EDIT: Yep, for me, that was the problem... updating to Sonama 14.7.5 has brought the analysis to life. Jordan, I suspect you have the same issue.
