[Migration] Unable to find the input element. It was resolved to [object HTMLDivElement] while an HTMLInputElement was expected.

• The issue is present in the latest release.
• I have searched the issues of this repository and believe that this is not a duplicate.

Current Behavior 😯

I am getting this error:

index.js:1 MUI: Unable to find the input element. It was resolved to [object HTMLDivElement] while an HTMLInputElement was expected.
Instead, Autocomplete expects an input element.

Make sure you have customized the input component correctly.

When I use autocomplete like this:

<Autocomplete
      freeSolo
      autoHighlight
      style={{ width: 350 }}
      open={open}
      onOpen={() => setOpen(true)}
      onClose={() => setOpen(false)}
      onChange={(_event, user) =>
        router.push(`/projects/${project.id}/users/${user.id}`)
      }
      onInputChange={(_event, newValue) => setValue(newValue)}
      isOptionEqualToValue={(option, optionTwo) => option.id === optionTwo.id}
      getOptionLabel={(user) => presentUser(user, project)}
      groupBy={(user) => capitalizeFirstLetter(user.userType)}
      options={options}
      loading={loading}
      renderInput={(params) => (
        <div ref={params.InputProps.ref}>
          <Input
            {...params.inputProps}
            variant="filled"
            className={classes.searchInput}
            classes={{ underline: classes.searchInputUnderline }}
            placeholder="Search"
            startAdornment={
              <InputAdornment position="start">
                <Search />
              </InputAdornment>
            }
            endAdornment={
              <>
                {loading ? (
                  <CircularProgress color="inherit" size={20} />
                ) : null}
                {params.InputProps.endAdornment}
              </>
            }
            type="text"
          />
        </div>
      )}
    />

It worked with v4. According to the documentation it seems like I am doing it correctly.

Expected Behavior 🤔

No errors should happen.
