This is expected behavior. You need to specify the date type.

not sure why this was closed. this error occurs in mui's internal code, not the user's code. you can see in the error he posted that it is coming from node_modules/@mui/lab/themeAugmentation/props.d.ts.
i'm seeing the same error in a codebase that isn't even using DateRangePickerDay.

it looks like we just need to change DateRangePickerDayProps<TDate> to DateRangePickerDayProps<TDate = unknown> in https://github.com/mui-org/material-ui/blob/master/packages/mui-lab/src/DateRangePickerDay/DateRangePickerDay.tsx#L44
