I've been able to spend a few more hours testing. Disabling Steam & Discord overlays has had no effect.
I've gone through a huge variety of combination of services in msconfig. Having everything disabled still provides the best results, and I've been unable to pin the issue on any single service.
A combination that seems to be working for me at the moment (10 minutes at main menu without crashing) is having the following services disabled:
- AMD Crash Defender Service
- AMD External Events Utility
- ASUS Com Service
- ASUS System Control Service
- ASUSFanControlService
- Corsair Gaming Audio Configuration Service
Not sure having these disabled is a viable long term solution though?
EDIT: The above combination crashed after about 12 minutes. It's feeling like a "volume of services" issue at the moment.
