I've been using Bandicam in Game Recording mode for a couple of years now, but it's suddenly stopped working. It is not recognizing the game window when I click on it. Screen recording mode still works. The game is Roblox, but I also tested it with Minecraft. Same problem, and both have worked before.
Possibly this is related to a Windows update which came through. There was some new setup when I logged in. I updated Bandicam to the latest version, but still no luck. Bandicam 184.108.40.2067
