Redux selector erroring when trying to export state in one slice but not another when the code is almost similar

Question

I am new to redux and I have created a slice called eventmodalSlice that is supposed to keep track of whether a modal in the app is open or closed. I get an error when I create a selector to export the state. The error says

TypeError: undefined is not an object (evaluating 'state.eventmodal')

import React from "react"
import { createSlice } from "@reduxjs/toolkit"

export const eventmodalSlice = createSlice({
    name: "eventmodal",
    initialState:{
        modalvisible: null
    },

    reducers: {
        Close: (state, action) => {
            state.modalvisible = action.payload;
        },

        Open: (state, action) => {
            state.modalvisible = action.payload;
        },

    }
});

export const  {Close, Open} = eventmodalSlice.actions;
export const selectEventModal = (state) => state.eventmodal.modalvisible;
export default eventmodalSlice.reducer;

I am not sure what causes this error in this specific slice because I have another slice called user slice which looks almost the same as this slice.

import React from "react"
import { createSlice } from "@reduxjs/toolkit"
import { act } from "react-test-renderer";

export const userSlice = createSlice({
    name: "user",
    initialState:{
        user: null
    },

    reducers: {
        Signin: (state, action) => {
            state.user = action.payload;
        },

        Register: (state, action) => {
            state.user = action.payload;
        },

        Signout: (state) => {
            state.user = null;
        }
    }
});

export const  { Signin, Register, Signout} = userSlice.actions;

export const selectUser = (state) => state.user.user;

export default userSlice.reducer;

State.user.user does not error in this last snippet. This is what's most confusing since these snippets look pretty much the same unless I am missing something. Any help would be appreciated here.

My store looks like this

import { configureStore } from "@reduxjs/toolkit";
import userReducer from "./userSlice"
import eventmodalReducer from "./eventmodalSlice"

export default configureStore({
    reducer: {
        user: userReducer,
        eventmodal: eventmodalReducer
    },
});
