Hey,
My MacBook Pro 2021 just broke a few days ago. Touchpad and keyboard started to not respond, then responded again, then no. Right now it's not working at all.
Once got a kernel panic too. I can't start the diagnostic tool because it says "Failed to start (or something like that)". well.
The Apple service told me it's liquid damage but I am pretty sure it's not the case.
Has anyone else had this and was able to repair it?
Everything working fine with an external mouse/keyboard.
