Nested VM Proxmox not working in Windows 10 2004 and VMWare WS 15.5.6 with AMD ThreadRipper 3970X

I'm trying to experiment with a lab running Proxmox VE under VMWare WS, and the VMs won't start in Proxmox. I've enabled AMD-V and counters.

Vmware version: 15.5.6 build-16341506

CPU AMD ThreadRippper 3970X on TRX-40 Pro Asus Mobo

256GB RAM

Windows: Windows 10, 64-bit  (Build 19041.450) 10.0.19041

Log file attached.

This is the error message we get trying to start VMs in Proxmox:

()

kvm: error: failed to set MSR 0xe1 to 0x0

kvm: /build/pve-qemu/pve-qemu-kvm-5.0.0/target/i386/kvm.c:2695: kvm_buf_set_msrs: Assertion `ret == cpu->kvm_msr_buf->nmsrs' failed.

TASK ERROR: start failed: QEMU exited with code

Saw that builds of win10 prior to 19636 did not support Nested Virt, so updated to latest insider preview, win 10:

Windows 10, 64-bit  (Build 20206.1000) 10.0.20206

Did not fix it.
