Cannot End Process or Properly Exit Game
 

So when I run the game everything is fine, runs great with no issues. I go to camp/exit and once the timer is up it freezes (according to my friend I'm sitting there but if I move then I still move with no action on my screen). I click the x button on the window and right click>close program and nothing happens so I go to close it through an end process from the task manager and it says access denied. I try end process tree and it says one or more of the processes could not be ended and the process couldn't not be completed. Only thing I noticed was for a while if I got stuck on the menu if I went to task manager, right clicked the process and unclicked uac virtualization it would let me end it but now it's greyed out and I can't end the process.
