MacBook Pro m1 2020 unresponsive keys and trackpad

Hi! No idea what’s happened with my MacBook, I was working on it and suddenly the trackpad would only right click - no left click. After restarting it worked again, and then the problem came back and about 3/4 of the keyboard is unresponsive. Tried rebooting/safe mode and can’t get passed the password stage because the keys don’t work. There is no water damage. Really strange and hopeful there is a solution here?
