Repro Steps
Boot machine, sit and wait. No other steps are necessary for this to happen on my machine. Not sure what I can do to mitigare this.
Expected Behavior
WSL2 should not restart network interface Hyper-V-VmSwitch every 2-10 minutes.
Actual Behavior
Every 2-10 minutes (sometimes a break of up to half an hour) Hyper-V-VmSwitch restarts it's network interface and logs it to windows logs, which causes sound stuttering on my usb headphones.
Networking driver in Virtual Machine is loaded and the protocol version is negotiated to the most recent version (Virtual machine ID 4E28C58C-BE6A-451D-A5E8-E944A5756E4D).
