I see the same error on Windows 2025 Standard.

Have Hyper-V installed and running, also when following the instructions in the error message "Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Hyper-V-Hypervisor" this error is returned:

It looks like there is some missing component in that Windows version that Multipass needs. We're working on a generalization of the Hyper-V backend that should hopefully work across the board, but it will take a little while before it's released.

Curious to know if there is any workaround in the meantime while this is addressed.
