Recent Update (August 2022) is back to constantly using 100%+ CPU

I've had nothing but problems with BitDefender using insane amounts of resources on my M1 MBP, but it's required for work so I haven't had another choice.

For the past month or so, the problems had mostly gone away, but after a recent update this month it's back to routinely pegging a CPU core at 100% (or even hitting almost 200% on multiple cores) after waking from sleep. The only fix I've found is to reboot, so I'm stuck rebooting my laptop multiple times a day to keep it from draining battery.

How do I even go about diagnosing this? It seems pretty easy to reproduce, just have an M1 MBP and use it.
