I think I found the way to solve this issue?
Although I gotta admit, it wasn't me who found it, I saw the comment saying this works on some YouTube video.
So basically I wanted to make a boot time scan and my PC got stuck in the infinite loading loop as well, even tho I left it for an hour or so.
For whatever reason, if you change your monitor refresh rate down to 60 and perform a boot Scan again it goes through just fine.
I did not do those geek area magic tricks, lowering HZ rate from 144 to 60 seem to have solved the issue and scan went through
Although there was no fancy blue screen, it was running in some bios-like environment with gray letters on the black screen and after the scan was done the PC restarted instantly
