In the hope that this catches the eye of someone on the development team…
The latest KDE ISO 21.1 RC2 (manjaro-kde-21.1-210723-linux513.iso) has a bug where it gets stuck during boot in a MHWD script in a VMWare Virtual Machine.
I know VMWare is an unsupported platform, but just in case it has an easy solution, because RC1 (manjaro-kde-21.1-stable-staging-minimal-210720-linux513.iso) works fine in the same virtual machine.
