Super weird keyboard bug ?

This is amongst the weirdest issues I've faced on this PC so far. For some weird reason the keyboard is acting finicky and it seems like it's not responding correctly. "Seems" being the key word, everything I write registers on the screen, but as I'm typing them it almost seems as if I'm deleting letters when I type. This is super hard to explain so I just recorded a vid of it happening. Google Drive link. (sorry about dirty screen) I am just spamming keyboard letters in this video and I didn't press delete at any point. It happens sporadically and unpredictably. For example right now it hasn't been happening for a while but when I recorded that video it was happening for like 30 secs straight.
