VIRTUALBOX MACHINE FREEZES

[ROGGER]

Good morning, I have created some virtual machines with Windows 10 Pro, Windows Server 2016 and Windows Server 2022, not all of them run at the same time, but the one with Windows 10 Pro and Windows Server 2022 suddenly freezes, even without doing anything I work on them.
Do you know if I have to have any special configuration on the host computer? It is a Dell G15 laptop with 32gb ram and 2tb ssd hard drive running Windows 11 Home Single Language.
VirtualBox version is 7.0.4

Thanks in advance.

Give the VM 2 CPU cores.

You have Hyper-v enabled on the host. This will cause VirtualBox VMs to slow to a crawl, so it likely isn't frozen, just very very slow due to running on 1 CPU core plus Hyper-v.

See HMR3Init: Attempting fall back to NEM (Hyper-V is active).
