/locate structure freezing nearly everything in superflat singleplayer

On my 1.19 Superflat singleplayer world which obviously doesn't have any structure generation. I did /locate structure, and it froze nearly all actions. After doing it, any command I put in doesn't do anything, nether portals don't work, and I cant load new chunks. The commands eventually go through but it takes upwards of 5 minutes. After a short while it caused any movement or action to be heavily delayed or just not happen. Trying to save and quit doesn't work either because it freezes on "saving world" and requires ending with task manager. I've tried multiple times to confirm it wasn't a random occurrence.
