It could be this annoying glitch in RT.
From time to time, it may happen that in the option file/GUI section, the two parameters WindowX and
WindowYare set to something like -32768.
In that case the RT window is lost off screen.
Setting these parameters to 0 cures the problem.
Or you get back the window on screen: https://www.howtogeek.com/howto/windows/bring-misplaced-off-screen-windows-back-to-your-desktop-keyboard-trick/
