Okey same problem with 3.2.9xx but I have some more information,
Besides the dmp file I sent you.
Here is how to reproduce it.
Windows 10 pro
Vpn PIA with split tunneling activated in OpenVPN,
Lan authorized, shadow socks activated ( so 2 relay points), personalized dns pointed to nextdns, most of the app bypassing vpn, only some throw vpn only.
You can maybe install parsec also just to remote view that test in a vm and check the cpu usage with system informer (former process hacker) and also the I/O input. You’ll see that gwctl absorb one entire core and goes up to 120MB/s in terms of io.
It does not happen with protonvpn: split tunneling also, but with wireguard and most of the app going through vpn besides some.
