Android Wireguard Unhandled Exception

[Silvan Nagl]

Hello,

herewith I want to announce a bug regarding to Androids Wireguard app.
The bug occurs when trying to start the app while the phone is still in
"lockdown mode". The lockdown mode was activated by my previous
l2tp/ipsec setup which was enforcing the VPN to be always activated. So
when I tried to start the Wireguard app the program crashed unhandled.
After I turned of the previous VPN setup it worked like expected.

Greetings

Silvan
