(An515-42) Can sleep mode crash by a defect keyboard?

Hello
I have an nitro 5 an515-42 with ryzen 5 processor.

On Windows 10 21h1 when i go to sleep mode after few Minute, the Laptop goes completly off and the lights on the jack led too. 
The Laptop is complety dead at this time, soft and hard battery reset don't work, no cmos reset work, unplug all drives and ram don't work, no battery replacement don't work or holding the Power button for a while to drain the components. 

After 2 days try and error i unplugged the wide keyboard flex cable for 2 seconds  put it back and after that the Laptop Jack lights goes on and Laptop starts normal and everything is fine. 

So, i tried sleep mode again and the same error occured, after flex cable reconnect everything works always as normal 🤷‍♂️

My question is can the keyboard crash sleep mode and a replacement would fix it? 

Sorry for my bad english 

Greetings
