Slate Plus V.4.4.5 - Wireguard still stop working after a couple of days

I am testing V.4.4.5 for the Slate Plus and even if release notes says “Fix WireGuard cannot reconnect after working for two days”, the problem is still there for me…
I am using the same WG configurations (Proton VPN) for Beryl AX, Slate AX and Spitz AX but I only have this problem on Slate Plus…

Problem still occurs for me as well. Woke up this morning after updating the firmware yesterday to the wireguard vpn being down.
