TOS6 wireguard network config

After migration from TOS 5.3.5 to TOS 6 my wireguard configuration stopped working and /var/log/messages is full of errors. Configuration in /etc/config/network that was perfectly fine for TOS 5.3.5 became useles. Were there any syntax change in the format of /etc/config/network for TOS 6 ?
LUCI wireguard section is also empty and does not show anything

my /etc/config/network wireguard config

config interface ‘wg0’
option proto ‘wireguard’
option private_key ‘CP/------------------------------------eJ2c=’
option listen_port ‘51820’
list addresses ‘192.168.245.1/24’

config wireguard_wg0
option public_key ‘unH5y-----------------------------------WD8=’
option route_allowed_ips ‘1’
list allowed_ips ‘192.168.245.2/32’
option persistent_keepalive ‘25’
option description ‘ONEPLUS8PRO’

error statements in /var/log/messages

Do you have WireGuard VPN protocol available in list of protocols in wg0 interface?

What does below cmd show? Not sure if you have correct module installed.

modinfo wireguard

How ? all config is done in /etc/config/network file and up is part of my file related to wireguard config. It is working perfectly under TOS 5.3.5 on my Turris 1x but when moved to TOS 6 on omnia (without any changes) it does not work at all.

It is part of content /etc/config/network file. In openwrt it is done via uci or direct file modification and wireguard config is part of this file.

omnia /tmp/log # modinfo wireguard

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: rtnl-link-wireguard

Imediately after attempt to setup new interface

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