Shift + s key not working in editor

Hi, this morning I can’t seem to be able to type capitalized “s” in the editor. I have no idea what went wrong. I did try out a couple of plugins this morning: mind mapper and day planner in particular, so I went and disabled/uninstalled both, but it hasn’t worked. I was also playing around in hot keys, so I went back and reset them all as well. Still, all of my keys work except for shift + s.

Hoping someone might know what’s going on. Thanks!

Things I have tried

Went through all hot keys, and even reset them all
Disabled community plug-ins
Restarted Obsidian and computer

does it work in the help vault?

It does.

delete .obsidian/config in your vault.

Solved! Thank you!
