Unable to open CMake on Windows 10

If I run cmake.exe form cmd line, it seems to work properly (I guess), no errors.
If I run the cmake-gui.exe from cmd line, the same thing happens as before and no output or error messages. (so I’m unable to do anything with the gui)
I was checking that, when the CMake GUI appears in the Windows toolbar and I hover on the thumbnail, it shows the last project folder, where I used previously CMake for building. So, might this be some problem that it remembers the last project and somehow tries accessing it? (picture attached on this)
