Sorry to hear that, but it seems you are not alone. I have a similar issue with TKL 2023 WL. After streaming for 5-10 mins with OBS (streaming + recording simultaneously) it starts pressing random keys. And that is every time I use OBS. Unplugging/plugging does not solve the issue, I need to stop the stream/recording AND reboot my machine (Windows 10). Uninstalling/reinstalling OBS and the drivers don't change anything.
It is very weird and I am suspicious about what this keyboard is doing in the background. Is Steelseries trustworthy? I wish for an expert to look inside the firmware or something like that.
I will open an issue if the next upgrade does not solve this and keep you up to date here.
