Bluetooth not working at all, internet not working at all, and even the setting for HDMI audio output is gone. The settings page is just empty.

I managed to load an older kernel(?) and got Bluetooth and internet working again, but still no audio. I’m as much of a novice at running Linux as you can get. I’ve been trying to troubleshoot this with the help of an LLM, but I have no idea what I’m doing here.

Any help, please?
