[icons] v7 "@mui/icons-material" typing is not working correctly for named exports

[laurence-hudson-mindfoundry]

Steps to reproduce

Minimal reproduction: https://stackblitz.com/edit/mui7-ts-icons?file=package.json

Current behavior

In v7 the wrong type information appears to be exposed for the index import path of "@mui/icons-material". The type information is that of a single icon (icon.d.ts) instead of named exports for all icons (index.d.ts). This issue is limited to the typing (the icons are actually importable as named exports).

import { AccessAlarm } from '@mui/icons-material';
results in
error TS2614: Module '"@mui/icons-material"' has no exported member 'AccessAlarm'

Expected behavior

Option 2 from the icon usage doc at https://mui.com/material-ui/icons/#usage should provide correct typing.

Context

I have offered some thoughts on a fix in MR #45695.

Have the same issue after the v7 upgrade

Same issue. Regression seems started on 7.0.0-beta.3 and it affects a stable release. 7.0.0-beta.2 works fine

We'll likely release a patch release before the weekend.

I updated to 7.0.1 and now the types are correct. Thank you!
