One channel of stereo channel lost

Hello all, after installing WL 11 EL I only have 1 audio output available (left or right). The same happened with Cubase 11 EL.
I am normally using Generic Low Latency Asio Driver. When I have Spotify or Netflix running everything is working fine.
I also have an external audio interface which works fine, but I want to be able to just plug headphones straight into the laptop headphones socket.
Anyone any idea?
Thank you.

Hi and welcome to the forum,

How does the Studio > Audio Connections > Outputs look like on your side, please?
