WireGuard for Windows crash "panic: ring is full" since release of 0.3.10

Mon Apr 12 07:56:04 UTC 2021

It seems to be your suggested workaround for using Wireguard via a split 
tunnel:

PostUp = wg set %WIREGUARD_TUNNEL_NAME% listen-port 0

which is causing the crash. It was great that this worked in earlier 
versions but I'm now back to square one.
