idk what to do

this happens on launch pad. no idea how to fix this.
purchased on steam, i launched a rocket and now when i launch anything the launch pad is vertical and the mouse seems backwards.
what i have tried to do to fix this:
reset all the options and controls in the options and settings.
uninstalled and searched for anything left.
reinstalled and its still there.
uninstalled and hit the checked save to cloud and reinstalled. (all my rockets were still there which i dont want it to do)

im not pc savy< and this will make me have a mental breakdown lol.
