Cannot Exit/Start the game

Whenever I try to play another Steam game, it always says that Game Dev Tycoon is running. I stopped all Steam process but whenever I boot Steam but up, it continues to say that I am still playing the game. I have wiped the entire game off of my desktop, but for some odd reason, it is still there. Could anyone help me get rid of this problem? Thanks.

On Windows, the process is called “nw.exe”, or if you’re on Linux…

Thank you! It solved the problem.
