Random Reboot Bridge OS on Ventura
My 2019 MacBook Pro is dual booting macOS Ventura and Tahoe. It used to run Ventura and Sonoma just fine, but after an upgrade, Ventura started randomly rebooting.
Sometimes the uptime lasts 2-3 hours before a reboot, other times it's barely 30 minutes before it crashes with a panic report (pasted below). This has had me worried for days.
I've already tried a PRAM reset and an SMC reset, but it's still happening. I suspect the version of BridgeOS might be the culprit.
I even created a partition to try and downgrade to Big Sur, thinking that might fix the BridgeOS version and the random reboots. But now the Big Sur installation just gets stuck on the loading screen. I read somewhere bridge os can be downgraded I don't have access to another Mac to create a bridge os version downgrade, and I'm honestly out of ideas.
Here is the panic report: """panic(cpu 1 caller 0xfffffff018c6d838): macOS watchdog detected
