Same here. I thought is was my CalDigit TS3+. I also have a OWC Thunderbolt Hub. My issue was it was on my 2019 MacBook Pro 16 (maxed out) running Ventura. I happened to have a 14" Apple MacBook M1 Max with 64GB, so I manually migrated my apps thinking it might be a software issue. I didn't migrate the usual culprits; AVG, CleanMyMac. Sure enough My system had issues with a LaCie External HDD, connected to the OWC, that I used for TimeMachine. It wouldn't stay mounted. Then on overnights - some maybe an additional clue - I'd come in in the morning, and the M1 rebooted. Kernel panic. Details below. I also swapped out the CalDigit TS3+ for a TS4. I never thought it could be the OWC, so I'll disconnect that to see if the issue goes away. I'm going to try some attempts to isolate. OWC currently connected via CalDigit. I'm going to connect that directly. Step at a time.
