MacBook Pro 2016 Touchbar Kernel Panics help

[EGT]

Hi,

I'd appreciate some help with some kernel panics I've been experiencing today.

I've had three kernel panics so far on the same day, which is unusual. Typically my Macbook Pro runs pretty flawlessly. The computer is a MacBook Pro (15-inch, 2016), 2.6 GHz Intel Core i7, 16 GB 2133 MHz LPDDR3, running Mac OS Sierra. Yes, I'm running an old system - I plan to update this soon.

No significant software or hardware changes recently apart from the apple system software update, which I installed last night; 10.12.6 - Security update 2019-004, Safari 12.1.12.

The kernel panic seems to happen when I wake the computer from sleep. After the second kernel panic, I booted into safe mode, which seemed to work fine, and then I restarted. I've been using the computer most of the afternoon until I closed it and went home. Upon opening the lid to use it this evening, it displayed the kernel panic error for the third time.

I've got several recent backups.

Any help or ideas very much appreciated. Kernal log below:
