WiFi connection drops when plugging in HDMI device

I have an M2 MacBook Air and whenever I plug in an HDMI device, the WiFi stays connected but doesn't transfer any data. The instant I disconnect the cable everything is back to normal.

I tested with a Hisense and a Samsung TV and with 2 HDMI Adapters with 3 cables and a direct USB-C to HDMI cable, all with the same outcome.

There are already several threads with the same topic here, but none of them has a solution.

How can it be that this still happens?

Maybe someone has a real solution to the problem?

I can only think that this is a problem with the Mac hardware or software. Every phone and a Windows Laptop worked as expected with all the tested cables and dongles.

I appreciate any help 🙂🙏
