Text in Photoshop invisible unless I zoom in or out
I started having this issue today, and I can't seem to figure out what's wrong. Photoshop worked fine yesterday, but now whenever I try typing something, the line that indicates the location where the letters are supposed to show up just moves but no letters show up behind it, as if I was just pressing space. The only way I can get to see any changes is when I either zoom in or zoom out, and sometimes clicking on another tool works, but not often. This happened very suddenly and I can't pinpoint what I did wrong. I would like a detailed answer please since I'm not very tech-savvy.
edit: I have 1 TB storage, 8 GB RAM, and CORE i7
