Keyboard, Trackpad & Bluetooth stopped working

Hello Everyone,

My magic mouse was connected to the system and i thought to close the lid of my macbook pro 13'' (2012) and put it for sleep. After few minutes when i opened it, all of sudden the first thing i noticed was, the Trackpad was not working, keyboard was also not working and the bluetooth sign now says "Bluetooth not available"

Following are the things i have tried so far.

• Boot the macbook in safe mode.
• Reset the SMC by connecting a windows keyboard. (WIDNOW + ALT + SHIFT + Power Button). I don't think it's getting reset because the magsafe light remains static and it turns on the computer normally.
• I tried deleting all the .Plist files located under "Preferences"
• Reattaching the keyboard & trackpad cable in the motherboard.
• Reinstalled the OS (10.15.5) - Fresh Installation
• Restored the time machine backup as well.
• Etrecheck Report is also attached.
