How can I open Windows Sandbox on Windows 10Pro VM using VirtualBox?

Question

I am trying to use Windows Sandbox for practicing malware analysis

My host machine is using Win11 Home, but my VM is Win10 Pro.

VirtualBox settings: Nested VT-x/AMD-V enabled, and my paravirtualization interface is set to Hyper-V.

On my VM I've enabled Hyper-V, Virtual Machine Platform, Windows Hypervisor Platform and Windows Sandbox.

On my host machine I've also enabled Virtual Machine Platform and Windows Hypervisor Platform. Virtualization is enabled in the BIOS as well.

I've also ran multiple commands like "bcdedit /set hypervisorlaunchtype auto" on both my host machine and my VM and ".\VBoxManage modifyvm "VMName" --nested-hw-virt on" on my host machine in my VirtualBox directory in order to confirm that nested virtualization is enabled. On my VM, running

"systeminfo | findstr /i "Hyper-V"' also returns confirmation that a hypervisor is running.

I've played around with checking and unchecking different things and trying different variations but no matter what I try, whenever I try to open Windows Sandbox on my VM it returns the message "No hypervisor was found. Please enable hypervisor support. Error 0xc0351000. No hypervisor is present on this system"
