Can't find .sty files after changing shell

I installed my texlive in

~/Software/texlive/2020

and when I used bash, I had

~/Software/texlive/2020/bin/x86_64-linux

in my PATH, which was all I needed to get all style files and packages.

Now I switched to zsh and added this directory again to my PATH but now compiler throws errors. I use vimtex for compilation, but I even tried using texstudio, and that also does not work.

What to do?

which tex even now gives
~/Software/texlive/20202/bin/x86_64-linux/tex
