Uncheck the “run as administrator” option and then select “OK.”
Under the “compatibility” tab, follow the same prompts above and select “OK” to save any changes made.

Press Windows + R type “taskmgr” into the text box. Then, select “enter.”
Once you are in the task manager, search for Discord processes. Click on it and then select “end process.”
