Game runs way too fast when exported as .exe in fullscreen mode

Hello! I have encountered an issue with exporting my game as a windows .exe file, as when I do the game appears to be running way faster (perhaps 2x the speed, more or less I don't know) in fullscreen-mode. It does not run at that speed in the game maker editor in fullscreen or in windowed. I am using the most recent version of Game Maker: Studio 2 and a 144hz gaming monitor from BenQ. The game FPS is set to 60 in GMS 2.

Any help would be very much appreciated.
Thanks!
