I managed to fix this and the 'Cannot install error'
Using a combination of the following (I don't know which worked)
Reset PRAM
Disable Filevault
Boot into Recovery and enable Startup Security
Use sudo sh -c "softwareupdate -ia" via terminal
Macbook 2015, Previously unable to restart with kernal panics and unable to install/download Public Beta 5

Same problem here.
Was on Public Beta 1 on Macbook 2015 running smoothly, attempted to update to Beta 5 (public beta 2), crashed while installing, the beta is now still present in system preferences however download won't complete, nor will install ever occur.
Have tried via terminal command line - no different.
