Cross posting my response from the in-thread forum:

It looks like

SC_PortAudioDriver: PortAudio failed at Pa_OpenStream with error: 'Unanticipated host error'
could not initialize audio.

is the problem. Sonic Pi uses the SuperCollider project for synthesis. SuperCollider on Windows relies on PortAudio. There's a (long) GitHub issue here about it supercollider/supercollider#3976 but it looks like they got it working eventually by updating their version of ASIO4ALL supercollider/supercollider#3976 (comment)

Could you check out that issue above and see if any of the proposed fixes work for you? I think this error might be specific to the combination of drivers and soundcards being used so it would be nice to figure it out for other users in future.

Closing for now due to inactivity.

We have completely overhauled the process with which we boot the system, and it would still be really great to know if this has somehow not resolved your situation.

Therefore, please feel free to re-open if this is still an issue with the recently released v4 of Sonic Pi - https://github.com/sonic-pi-net/sonic-pi/releases
