After the upgrade to Catalina, as everyone else, I couldn't use anaconda. At the end I erased everything and downloaded it again to install it from scratch. I am using Mac OS Catalina 10.15.7 During installation it says 'unpacking payload' and it extracts some files. After that, nothing happens, no error message, nothing. It just shows the prompt again. If I go to /Users/user/anaconda3/ there are only a few files (Licence.txt, conda-meta, conda.exe, pkgs, postconda.tar.bz2). There is no bin folder. There is nothing installed. 
I have tried with bash, with zsh, with different anaconda versions. From version 2019.7 to 2020.11 it is the same thing.
If I use version 2018 to 2019.3 it does continue with the installation, however it does not run anything. I tried conda list, conda update, conda upgrade, conda install  and all of them encounter 'an unexpected error' 

I would appreciate any ideas of what could be happening and how could it be solved.
thanks

Run via bash -x and paste the output from the shell based installer please.

it is weird that it tries to run conda.exe
instead of skiping the conda.exe line, it asks for y/N. It exits whether I put yes or no.

SOLVED I finally solved it. I erased the .condarc and .conda folder in my home directory. Then I ran the installer again and it worked.

It seems that the problem was that everytime I was trying to reinstall anaconda I was only erasing the anaconda3 folder and not the files/folders hidden in the home directory which were causing the issue.
