socket-vmnet error while launching VM

[Ranjandas]

I have someone run into an issue while launching Lima VM using socket-vmnet. It had worked before but stopped working all of a sudden.

$ limactl start template://alpine --network=lima:shared

Tried running socket_vmnet manually and it throws the following error:

Not sure what exactly the issue was. But stopping and disabling multipass got it working again. This thread can be closed.
