@CaseySJ A bit more info on my issue with windows 10 crashing when booting from the OC picker. I have plugged in a Windows 10 bootable NVMe drive which is in a usb-c enclosure. Upon starting upon the system, the usb drive appears in the Oc picker. When I select it, same issue: windows logo spins for around 2-3s then blue screen with error code: acpi_bios_error stop code. So definitely something with OC picker since version 0.6.2.
I have looked on the net for various solutions, tried most of them but still no luck.
Also read that the main issue is that OC injects ACPI to all OSes including Windows. One solution was to add if(_DARWIN) to all SSDT under "methods". All my SSDTs have that statement except for DTPG. So following so guides I disabled it, rebooted windows and same issues. So I am stuck at this point is time. another solution is pointing at using rEFind bootloader instead of the OC bootloader but I'd rather stick to OC.
I also mounted my windows EFI partition. Here is a screenshot. does that look ok?

In particular the boot folder (not the one under microsoft) which contains bootx64.efi
