As we switched the installer it might be that this is causing the issue for you.
It would be very nice of you if you could try installing again by executing the installer from the terminal by entering
pkexec calamares -d which should give debug output on the terminal. Please log this output to a text file while installing and attach it here in this forum thread so we and also the developers of calamares(the new installer) can take a look
