I have an ASUS TuF Gaming Laptop with AMD Ryzen. Till yesterday, I has Windows as my OS. But yesterday, before shutting down, it displayed – "Windows Crash Error in a Blue Screen – Your PC Has crashed :("

It then entered in Bios Asus Utility EZ and has been running in loop since then. I tried

1. pressing F10 (Save and Exit)

2. Changing Secure Boot – Disable

3. Fast Boot – Enable

4. I don’t have Launch CSM Option in my laptop.

5. Nothing happened even after pressing F10.

Then, I pressed ctrl+alt+del (in bios menu) and esc key while asus came up, it led me to "Please Select Boot Device" –

Here I just have Enter Setup option and no windows Bootloader or any other thing.
Error Coming Up

Till yesterday night, my Windows was fine. I am now afraid if my Windows crashed and everything is deleted. Can somebody help me resolve this error and get me back to my windows?
