kernel panic remains after a week of troubleshooting - what is next?

15" MacBook Pro (2018)

Ventura 13.2.1 installed (and reinstalled twice through out this process)

Peripherals normally in use (kernel panic present regardless of peripherals in various test scenarios)

• Apple Thunderbolt external Monitor
• 2 external SSD (Samsung T5 and T7 2tb each)
• apple blue tooth keyboard and mouse

symptoms (various over the past 7 days)

• computer restarts after having experienced an " issue" (after having been in sleep mode)
• computer freezes while in use (various apps, including etrecheck- no discernable pattern) and requires hard reboot
• computer goes through crash reboot cycles - usually 5 reboots, and then opens with the "Panic Medic Boot" message - "A third-party kernel extension was preventing the machinde from successfully booting..."
• selecting "restart" from apple menu will freeze the computer and require a hard reboot
• selecting "shut down" will shut down the computer as intended. (then pressing power button to begin the reboot/crash cycles)
• computer discovered with a dark screen (but definitely state with Touch Bar awake - but the computer is non responsive - requires a hard reboot

troubleshooting

• progressed through all steps shown here - If your Mac starts up to an Apple logo or progress bar - Apple Support
• included multiple disk-utility "repairs", SMC/NVRAM reboots, and two re-installs of Ventura from Mac OS Recovery
• laptop boots without issue in SAFE mode
• ran etrecheck reports after each incident, and uninstalled various third party apps identified as potential issue, updated all remaining third party apps.
• tested repeatedly both with and without peripherals attached - and today - after having removed all potential problematic files and apps, I removed all peripherals to test the start up once again - and experienced the largest number/variety of symptoms yet - apps "not responding", ongoing crash reboot cycles, stalled startup - requiring forced restart.
• I'm now operating in safe boot mode without issue to write and post this...
• first report ran on 20Feb, final report run 27 Feb (15 reports total).
• the last few days of etrecheck reports show a single kernel panic line item -

 2023-02-27 14:53:20 Kernel Panic (158 times)

        Details:

            panic(cpu 1 caller 0xfffffff01570db08): macOS panic detected

            Panicked task 0xffffffdf23171638: 0 pages, 224 threads: pid 0: kernel_

     task

my question - How do I identify, the apparently single, "third-party kernel extension" (referenced in the Panic Medic Boot message, and I assume in the etrecheck report diagnostic cited just above) that was preventing the machine from successfully booting, in order to eliminate it?

Thanks in advance for your time in reading this much and for anyone who has experienced and/or resolved something like this previously.

Final Etrecheck report is included as well for refernce
