WSL2 Unable to Install/Upgrade Distros 18995.1+ #4573

Build: 10.0.18995.1

I tried really hard not to open another issue here but I'm not having any success with WSL2 on latest build. The following issues may be related as to why:

• Attempts to convert working WSL v1 distros fail with prompt to enable Virtual Machine Platform feature (tested w/Ubuntu 18.04 LTS from Store)
  

• Attempts to install new distros after setting wsl default version to 2 fail with error 0x80370102
  

• Conversion attempts also prompt a Defender notification (I have automatic sample submission turned off)
  

Before Creating Issue

• I triple checked my BIOS virtualization is enabled and verified via Task Manager & multiple motherboard/BIOS config apps (ASUS utilities)
• Tried enabling/disabling/re-enabling of the Subsystem for Linux & Virtual Machine Platform features via both PowerShell & Features GUI (with restarts between each individual feature)
• Tried fully disabling Defender/Firewall protection
• Because researching docs/community still left me unclear on Hyper-V as it relates to WSL2, I tried enabling/disabling Hyper-V & Windows Hypervisor Platform features via both PowerShell & Features GUI (restarts between tests)
