You can now download and install a binary deb file for Sonic Pi 4.6 which I have built to run on a Raspberry Pi running the official raspberry pi bookworm (64bit version) OS. I have tested the installation on both PI5 and Pi4
You can download it from sonic-pi.net#rp
Note it will also install qpwgraph which is a graphical program which you can use to configure the input and output routings of SuperCollider.
Also see my video showing the use of this on the previous version of Sonic Pi
