After I opened the program, it couldn't be found at all on my desktop, but it is currently running and can be captured using OBS. May I ask what is the solution? The same result applies to reinstalling after uninstallation.
Hey, sorry you're running into this issue. This usually happens after removing a monitor that was plugged in and had MiniMeters on it. If you follow the steps here it should correct it: https://minimeters.app/help/behaving/
Afterwards, make sure "Reposition Offscreen Windows" is enabled in the settings and it should no longer happen. Let me know if you need additional help!
