TOS6 wireguard network config

Do anyone archieved to setup wireguard on TOS 6 Omnia succesfully ?
I tried after some time, newer kernel same kernel fault issue.

Following exact steps from this Turris Academy - new date announcements & recorded TAs to watch - #7 by F.B turris academy video with same results.

Before attempt to setup new wireguard interface, kernel module is loaded
module: /lib/modules/5.4.203/wireguard.ko
alias: net-pf-16-proto-16-family-wireguard
alias: rtnl-link-wireguard
license: GPL v2
depends: udp_tunnel,curve25519-neon,libchacha20poly1305,ip6_udp_tunnel,libcurve25519-generic
intree: Y
name: wireguard
vermagic: 5.4.203 SMP mod_unload ARMv7 p2v8

Imediately after attempt to setup new interface

Do anyone use wireguard on HBL or not ? Is it known issue of TOS6 or not ?
