Glitch or bug, every time i quit the game it creates a new profile called Debug Client profile1 and im unable to access my characters or switch back to my original profile.
Sounds like you started it twice. Wait a bit rather than spamming it. DebugClient is the default if you start a second (or more) instance of the game.
You can copy save games from one profile to another if you want. Just copy the relevant directory. You get most things copied but there are some minor things that are profile based rather than game based so if you want to change, I don't know, Panning Speed, you'll have to update that.
