Documentation for version 4-11.4 of material ui is missing

You can find old documentation here:

https://v4.mui.com/

Might be related: https://github.com/mui-org/material-ui/issues/28368

You can get the previous versions from git.

Clone the branch with the version you want

git clone --single-branch --branch v4.11.4 https://github.com/mui-org/material-ui.git

Then cd to the folder

cd material-ui

Run it as dev (faster but has to compile individual pages)

yarn && yarn docs:dev

Or build and start it (a bit slower but worth it)

yarn && yarn docs:build && yarn docs:start

Then access it in http://localhost:3000/

You must use yarn, npm install --global yarn if you don't have it
