Manjaro - unable to log in

I want to preface this by saying, I am quite a noob when it comes to linux. I also use dualboot for windows and manjaro, both on separate SSDs.

I booted into my Manjaro KDE, however I am unable to actually log in with my correct password. I input my password, correctly log in, get like 2 seconds of blackscreen before getting booted back to the log in screen.

Last major thing I did before this was add an fstab line of mounting for my HDD, which I was unable to access beforehand, so I thought it'd help.
