Found a Solution:
- While using a a live USB boot into manjaro with Open Source Software.
- DO not Start Calamares
- Open KDE Partition Manager.
- Now KDE Partition Manager will work fine and Format the SSD or HDD with ext4 you want to install Manjaro on
- After success, reboot and then Again go into live USB with Open Source or Propitiatory Drivers, and it will work fine.
Thanks All for Helping me you all guys.
I was using Ubuntu Before Manjaro, I never regret moving to this distro, and I have even uninstalled windows 10 now.
