Game screenshots automatically

Earlier today, I was changing keybinds for screenshot (originally Alt+O). I don't remember what I changed it to but now I can't do anything. The game launches but everytime I click or press a key, the game opens chrome and shows a screenshot. I don't know what to do. I reinstalled the game but the problem persists. Is there a way I can reset the settings without going into the game?

i think it was set to left click.

 

if you delete the contents of appdata/local/beamng/ (not including your mods and screenshots) it should revert

 

Hello. Where can I find this file? In my Steam folder?

 

as in c:/users/user/appdata/local/beamng.drive/

 

Thank you this worked.

Quick question. Why does my disk lose space everytime I load up a map? The space loss differs on each map.
