RP4 doesnt show up in imager or computer

Tried plugging it into my macbook and windows PC, its not a micro SD card issue because when i plug it in by itself it works fine, light is solid red and im connecting via USB c

Doesnt show anywhere in either file system or the imager

Also have tried 2 different cables

And 2 different sd cards

If you want to install the operating system, you must insert the SD card directly into the Mac or Windows PC. Or you can connect the monitor, keyboard and Ethernet cable to the Raspberry and press Shift on startup, then you can install the operating system via net-install.

Solid RED = It has power Blinking GREEN = Activity, the Pi is alive.
