Hi um, a Proxmox beginner this is my first install. need help with this issue i am having

I created a TrueNAS Scale VM and it comes up with this error below when I try to start the VM for the first time.
I had changed the processor type to Sandy Bridge when creating the VM hoping it might solve the issue.

kvm: warning: host doesn't support requested feature: CPUID.01H:ECX.aes [bit 25]
kvm: Host doesn't support requested features
TASK ERROR: start failed: QEMU exited with code 1

Below are the host specs um running it on an old desktop processor in an intel Core i3-2100 2C4T, Ram is 8GB i have a 256GB SSD as the main drive.

Try changing the cpu type to kvm64 or host

you can also try to disable aes flag in cpu advanced option. (seem that this processor is really a sandybridge, but aes was not present on these desktop model).
