Sonic Pi v5 not Booting on Win 11

Hi everyone. I was completely unable to get Sonic Pi 5.0 to open on my machine—it consistently crashed during bootup and generated timeout logs. I spent some time troubleshooting the logs with the help of Gemini, and we put together this summary of the exact failure points: ### **Bug Report: v5.0.0 Boot Timeout (SuperSonic/DirectSound) and audio-settings.toml parsing failure** **System Information** Sonic Pi version: 5.0.0 OS: Windows 11 Version 25H2 CPU: x86_64 **The Bug** Sonic Pi 5.0.0 fails to boot, resulting in a Critical error! Could not connect to Sonic Pi Server. The GUI reports that the SuperSonic audio server timed out after 30 seconds and never answered the boot handshake. When attempting to force SuperSonic away from the default DirectSound driver using audio-settings.toml, the Daemon completely ignores the configuration file, returning an empty hash. **Troubleshooting Steps Taken (with no success):** - Checked Device Manager and disabled conflicting virtual audio cables (VB-Audio) and "Hands-Free" Bluetooth profiles. - Ensured Windows Audio sample rates matched (48000 Hz). - Attempted to force WASAPI ("Windows Audio") and ASIO using audio-settings.toml (uncommenting sound_card_name and using the scsynth_opts_override escape hatch). - Verified the config file was named exactly audio-settings.toml (not a hidden .txt extension) and saved with UTF-8 encoding. **Key Log Findings:** - supersonic.log: The engine defaults to DirectSound and immediately suffers a wall clock drift, failing the handshake. - aboutToStart: device='Primary Sound Driver' type='DirectSound' [synth] DRIFT: wall clock +108.9ms from audio timebase, re-converging - daemon.log: The Daemon fails to parse the config file entirely, meaning it is impossible to manually route the audio engine away from the crashing DirectSound driver. - Got Audio Settings toml hash: {} **spider.log:** - Warning: /supersonic/notify registration timed out (30.0s) ### Workaround (?) I completely uninstalled version 5.0.0 and installed version 4.6. After removing the audio-settings.toml override file, version 4.6 successfully booted using its default engine settings. Is there anything I can do to install v5?
