I live in Houston where there can be up to 80% humidity in the air… as long as you don’t move the PC into the room with the shower you should be good. Run the fan. Keep the door open so the humid air mixes with the less humid air. You should be fine.

Open task manager and see if it seems it as frozen

There used to be a bug in the Zoom install that after you uninstalled it, Zoom kept running anyways. So they can do anything they want.
