Hi,
I've noticed a problem with my MacBook Pro randomly kernel panicing and rebooting. I have sent my machine off to AppleCare for it to be looked into, and since then I've been working off another MBP that my work have provided. After installing all the software I needed and working away for a while, I started to get kernel panics again, which leads me to believe that the issue is either something to do with software I have installed, or peripherals I have attached to the MBP I'm using. I've got an EtreCheck report below. Can someone help shed some light on this please?

Kernel Panics are predominately caused by hardware faults or faulty third-party kernel extensions.

To trouble shoot further you can:
—Try a SafeBoot https://support.apple.com/en-us/HT201262
Takes noticeable longer to get to the login screen, does a 5 minute disk repair before it fully boots up, and certain system caches get cleared and rebuilt, including dynamic loader cache, etc.
Login and test. Reboot as normal. Caches get rebuilt automatically.
In Safe mode third party system modifications and system accelerations are disabled, it removes malware, etc hampering smooth operation, however a reboot will put it back to normal mode.
This test will tell you if third party interference; extensions etc are not loaded in safe boot mode.
—Test issue in another user (or guest user) account https://support.apple.com/guide/mac-help/set-up-other-users-on-your-mac-mtusr001/mac
This will tell you if it a universal issue or isolated to your user/admin account.
Uninstall all third party apps that are Cleaners/Optimizers/VPN/Anti-Virus
