I had this same problem with MacWise and discovered that it is caused by trying to use any other shell except for zsh with Big Sur.
If you try to open a session with tcsh shell, it lets you type and echos characters back to the screen as you type. But if you request data from the shell (just do a simple ls) you get no response.
Then what is really strange is after doing that, run Terminal and you get the exact same symptom.
Rebooting is the only thing that gets you back to normal.
I am the developer for MacWise and have modified the latest version of MacWise to only use the zsh shell and it works with no problem.
I filed a bug report.

This might be a bug in the beta 5 installer.
I have the same problem trying to upgrade from Ventura beta 3 to beta 5.
It downloads the beta 5 upgrade and restarts the Mac but never installs the new beta.
I am running an M1 Mac Mini.
BTW, can someone tell me how to install the Download Restore Image?
It is an ipsw file and I can't figure out how to install it.
No work-around for me. I even tried reformatting my external drive and installing Monterey. Then tried the Ventura beta install with no luck.
