my macbook air 2017 suddenly developed the following issues:

  1. trackpad and keyboard suddenly stopped working

  2. I am running in bootcamp, but I am no longer able to go back on MacOS

  3. Cpu Usage spikes to 100% when doing simple tasks, like opening google chrome

  4. In the device manager, there is an "unknown usb device (device descriptor request failed)"

  5. Memory usage in task manager always at least 38%, the sum of the memory used is less than 500mb but my machine has 8 GB RAM.

  6. USB keyboard and mouse works but not the internal trackpad and keyboard

I suspect 4. is the root of the problem because a windows notification popped up about the "unknown usb device" and that's when the keyboard and trackpad went unresponsive.

Does anyone know how I can fix this?

Edit: Also I did a windows memory diagnosis and no errors were found.
