I use an Apple Silicon Mac and often use programmable keyboards like the Royal Kludge RK61 via USB C. when I press keys such as A, S, D, F, W, or nearby keys in quick succession, the keyboard stops responding completely until I unplug and reconnect it. I've even replaced the USB C cable with a new store bought cable, but the issue still persists.
Check if your keyboard has a way to enable n-key rollover (NKRO)

You are genius! thanks this completely solved my issue, for those curious https://postimg.cc/75hV9tCK
I use usevia, all i had to do was find a keyboard definition file for my keyboard which claude found in 2 minutes!
Usb isn't the issue, you bought an extremely budget mechanical keyboard.
Also avoid Epomaker, had the same issues, but needed a full reflash (every other day), losing all my layers etc. (The import function was broken lol)
turns out it was just me not knowing my keyboard has full qmk support and can be configured via usevia, what N-key rollover (NKRO) is.
my keyboard is actually r65 by royal kludge i got that wrong!
I was gifted this keyboard and i just love its feel.
