Trying to insert a picture of the tiny little window that pops up after launch.
I know exactly what you're seeing, one of my CC members has the exact same thing. I, myself, recently had the golf.exe file disappear and after uninstalling and reinstalling the game it still didn't come back. Deleted the WGT launcher folder and did it again. Nope, file's still gone.
This is what fixed my problem and is what I advised my CC member. Haven't heard back from him yet.
Delete your desktop icon. Go to the Topgolf folder in your system files (C: Program Files (86)/Topgolf) and create a new folder in Topgolf. There should already be one there called WGT Launcher-ignore it. Create a new one and call it something else.
Now, when you download the launcher and it asks you where you want to put it, navigate to that folder you just created and have it install there. Yes to the desktop icon and Quick Launch bar (optional). Close everything. Your WGT Launcher folder is now brand new and located in a new place-that new folder you created. Start the game and see what you get. Deleting the original golf icon is crucial. If you don't it'll take you to the bad folder. Let the program install new ones because the link is different now (new folder.)
It sounds like you have a bad file (guessing) and even though you delete the launcher it's sticking around someplace. Creating a new place for the game to start from leaves whatever was causing the problem in the original folder. Eff it. LOL
