@RKM I apologize for the delay in response. I took a hiatus on the project and haven’t checked on this forum in forever. My PC actually died awhile back and I recently got it going again. I’m in the process of reinstalling all my development tools now so fingers crossed everything still works.
I honestly have no clue what the issue might be. Does it show up in task manager or on your start bar?
If it shows up on the start bar make sure you have it selected then press “Alt+Space” then “M” then either the Left or Right Arrow key. That will snap the window to your mouse and you can move it back onto your screen. It’s possible it’s opening off screen especially if you use multiple monitors or a projector sometimes.
