The other option is exiting the game and heading to the installation folder. There, you will find the file names user.settings, and tap to open it using a text editor. Search for fullscreen=true and change it to become fullscreen=false. This will change the game to run in windowed mode. Moreover, you will need to disable any third-party software you may be using since they may be the reason for the interference with your game’s windowed mode.
You may try to launch using the borderless mode from the game’s options. If the problem does not stop, switch it to windowed mode and back again to borderless mode.
