Manjaro does not boot after update - emergency shell

Hi @GaVenga, in case I didn’t make it clear, the screenshot with Memory Tester is just to demonstrate to @TriMoon what screen I used to see for login. That picture is from a guide to set up dual boot, it’s not from my system.

Both my OS, Manjaro and Windows are UEFI. I know this for a fact as I had to reinstall windows in October before installing Manjaro.
