SSH handshake failed on Windows 11 Hyper-V - VM receives only IPv6, network adapter not auto-configured

[JJM-System]

CRC fails to establish SSH connection on Windows 11 Hyper-V. VM is created and running but:

• SSH connection fails: "handshake failed: wsarecv: An existing connection was forcibly closed"
• VM receives only IPv6 link-local (fe80::...), no IPv4
• Port 2222 listening but connection refused
• Root cause: crc setup/start does NOT automatically create/configure network switch and adapter

Environment

Property	Value
OS	Windows 11 Pro 10.0.26200
CRC Version	2.55.1+6252bc
Hypervisor	Hyper-V (HypervisorPlatform Enabled)
CPU	Intel Core i7-13850HX
VM State	Running (verified via Get-VM)

Actual Behavior

After crc setup and crc start:

• Get-VMSwitch shows only "Default Switch" (switch "crc" never created)
• VM has no IPv4 address, only IPv6 link-local

SSH error:

ssh: handshake failed: read tcp 127.0.0.1:50200->127.0.0.1:2222:
wsarecv: An existing connection was forcibly closed by the remote host
