Current behavior

Hi, the issue come up only with the version 6.1.0 but was not present in the preview version 6.0.2. Even the version 6.1.1 (last release) not solve the problem I had the issue the NavigateBefore and NavigateNext but not with DoNotDisturb The returned error is Resolving to directories is not possible with the exports field (request was ./)

I use the following code in same file

import { DoNotDisturb } from '@mui/icons-material/';                 // working
import { NavigateNext } from '@mui/icons-material/';                 // not working
import NavigateBefore from '@mui/icons-material/NavigateBefore';     // not working

Thanks a lot for your awesome work
