MacBook Air Kernel Panics and freeze up

Hello,

For the past several months, my MacBook Air fails after a few minutes of inactivity. It either freezes (display frozen, mouse and keyboard unresponsive), or it shuts down completely. I've installed EtreCheck, and the shut downs seem to be related to kernel panic events. I've not been able to figure out any correlating events with the freeze ups.

I've contacted Apple Tech Support, and they suggested I reset the NVRAM and SMC. They also suggested I set up a new user and see if the situation occurred with a "clean" user profile. I've done each of these steps multiple times with no effect. I've also removed almost all of the third party software on the machine, with the exception of EtreCheck and Malwarebytes. I removed Malwarebytes a few days ago however, but reinstalled it after seeing no change in the problem.

Attaching a recent EtreCheck report. There is an item in this report related to high CPU utilization. I believe that is a red herring. Given the instability of the system, I replicated about 500GB to iCloud, and backed the machine up to and external USB drive. I believe the instances of high CPU utilization are related to those activities.

Appreciate any advice the community might have.

Thank you!
