Module parse failed: Unexpected token (256:34) You may need an appropriate loader to handle this file type

Two days ago everything was working perfectly, two days has passed and all of the sudden I get errors like these all over my components. If I "fix" one the next comes up. Can you please point me the source of these errors. I have absolutely no idea what is the problem or how to sum it up to a more precise question..

here is the rest of the project: https://github.com/donev-stan/internship-app/tree/main/internship-app

Here is the component I am trying to fix now:

import React, { useEffect, useState } from "react";
import { Link, Navigate } from "react-router-dom";
import { getLoggedUser, logout } from "../../core/services/AuthService";

import Container from "react-bootstrap/Container";
import Nav from "react-bootstrap/Nav";
import Navbar from "react-bootstrap/Navbar";
import NavDropdown from "react-bootstrap/NavDropdown";
import Modal from "react-bootstrap/Modal";
import Button from "react-bootstrap/Button";
import Row from "react-bootstrap/Row";

import logo from "../../images/logo.png";
import { deleteStudent } from "../../core/services/StudentService";
import { deleteCompany } from "../../core/services/CompanyServices";

const Header = () => {
  const [user, setUser] = useState(null);
  const [redirect, setRedirect] = useState(false);

  const [showModal, setShowModal] = useState(false);

  const handleClose = () => setShowModal(false);
  const handleShow = () => setShowModal(true);

  useEffect(() => {
    setUser(getLoggedUser());
  }, []);

  const userLogout = (e) => {
    logout();
    setRedirect(true);
  };

  const userDelete = () => {
    if (user.type === "student") {
      deleteStudent(user.id).then((_) => {
        setRedirect(true);
      });
    } else if (user.type === "company") {
      deleteCompany(user.id).then((_) => {
        setRedirect(true);
      });
    }

    handleClose();
  };

  return (
    <Row>
      {redirect && <Navigate to="/login" />}

      <Modal
