Do you have a test file that you could attach to your message, reproducing this behaviour? I'm not a biber (nor beamer) user myself, so it's hard to guess what can be happening.

Tests I've done so far, based on some of the error messages on your screenshot:


% file /Library/TeX/texbin/biber

It doesn't tell much, other that some of the elements reported missing on your screenshot seem present on my setup (macOS Ventura 13.0 Beta 8, Xcode 14.1 Beta 2, MacTex 2022, Apple Silicon M1 processor). But I've no idea whether that's relevant.
