Bug Playtest mode loads eternally

So, I have a small project that I'm working on, and earlier today when I hit the Play button to playtest it would load in a matter of seconds. While testing some code edits, however, I tried to re-enter playtest mode again to see if it was working, and it then froze. There's a progress bar showing it's "waiting for Unity's code to finish executing" and seems to be trying to load Application.EnterPlayMode, and the progress bar shows a green line moving across the screen, but it will stay in this state for as long as I leave it. Last time it made it to nearly an hour and as I type this now it's at about 15 minutes.

This is not a large project (yet), it should not be taking this long to load whenever I try to playtest a scene.

Unity version: 2022.1.11f1
