Segmentation fault after install

I did what I could to remove the last versions of conda and psi4 I had: deleted the my psi4 directory as well as ~/.zshrc and the psi4 stuff in ~/.zprofile, and restarted the shell. Is there anywhere else I should check? If there is still some hanging around, it could have been where my problems came from.

I installed miniconda, and that seemed to go fine, but when I ran conda install psi4=1.4rc1 psi4-rt=1.4.dev30 python=3.9 -c psi4/label/dev , conda gave a lot of errors.

I’ve added the full out put as an attachment, but here are the highlights:

The following specifications were found to be incompatible with each other:

After that there are a lot of package conflicts, and:

% psi4 --test
zsh: command not found: psi4

I don’t really know anything about conda, any suggestions for how to fix this are welcome, thanks!
