I am running the following:
Issue manifests on Canary and Dev Builds (Beta is Stable) Issue only manifests when Profile Sync is enabled. Browsers will close within roughly 30 seconds from start.
OS Type: Win10 Pro 64bit 19H2 Build 18363.476
AV: Windows Defender
Anti Malware: Malwarebytes (Premier) build 3.8.3
Attached is the event logs.. not much helpful there though..
@HotCakeX it appears that Canary Build Version 80.0.344.0 (Official build) canary (64-bit) is stable.
Thank You =)
