Cannot install shell installer via "bash" command at macOS Big Sur beta

Recently I've installed (p.s., not upgraded, meaning I erased all the file before installing the beta OS) macOS 11 beta (Version 11.0 Beta (20A4299v)) and found the following issues with the Terminal.app.
  1. Tried to install miniconda with the following command at Terminal.app. However, it simply does not work. I tried to replace the bash shell with the zsh one. Same result. I believe the bash command does not work in this macOS beta version neither in the zsh shell nor in the bash shell.



Code Block bash
bash Miniconda3-latest-MacOSX-x86_64.sh

2. Another issue is that, after using iTerm.app, the Terminal.app CANNOT be open "again" (nor can I open another window of the iTerm.app), and the Mac cannot be shut down normally thus I had to firstly, force shutdown the Mac and then uninstalled the iTerm.app.

Many thx.
The part I has been solved by conda:


Code Block terminal
source <path to conda>/bin/activate
conda init zsh


The part II has been solved by macOS Big Sur Dev beta 2 lol
