"Preparing Automatic Repair" infinite loop

Hi all, I fresh installed Windows 10x64 in my new laptop. It was working flawlessly. The main drive is a Samsung EVO 960 Nvme. All I did was temporarily replace it with another SSD (I had to test it), and then reinstalled the EVO. Upon reinstalling it each time I power the laptop the following message is displayed:"Preparing Automatic Repair", it then goes on into "Diagnosing your PC" and after that a blue screen shows up with "Automatic Repair couldn't repair your PC" with the option of a "Shut Down" button, and "Advanced Options" button. I tried "Advanced Options", "Startup Repair" but it couldn't fix it.
In the first place I wonder why this happened? All I did was remove the drive and then reinsert it. And then I'd appreciate if anyone can suggest a fix without having to reinstall WIndows, which is a lot of time spent. Thanks.

Thanks, unfortunately I had to reinstall Windows since I had the original Windows encrypted with Veracrypt and the C: volume was unrecognizable ("unknown format"). There was a workaround I could've tried (boot from the encrypted EFI and decrypt the drive) but I decided to go for Windows reinstall. I always make an image of my drives but unfortunately I hadn't in this case. Fortunately it's a new laptop and my main Windows/Data is in my PC.
