Help installing Octave 6.1

Dear all, I believe this is the right channel to write this query, sorry if
not!

I'm trying to install Octave 6.1 on my Windows 10 PC and I can't make the
GUI work properly. After installation I execute the GUI and it just do
nothing, never opens. I tried to execute the CLI and it opens the command
windows but I can't make the GUI works. I tried different installations but
produces the same result.

I've also installed in my machine the 5.1 version and it works perfectly
fine, I can't uninstall it because I need it. Even version 5.2 works fine
but it has some kind of bug wich makes the GUI hangs suddenly and it is not
useful for me..

Please, would you give some guidance on this in order to make it work?
Thank you very much in advance
Best regards.
