How to send images out of database from fragment to fragment in Android Studio using Glide

I try to send an image that is stored in the database from one fragment to the other. In the first one (using a recyclerview) it gets displayed, but in the second one (normal fragment) it doesnt work and i get a permission error. I have given the required permissions in the manifest (otherwise it wouldnt work in the recyclerview).

Here it works fine:

package com.example.travelfriends.data

import android.net.Uri
import android.util.Log
import android.view.LayoutInflater
import android.view.ViewGroup
import android.widget.ImageView
import android.widget.TextView
import androidx.recyclerview.widget.RecyclerView
import com.bumptech.glide.Glide
import com.example.travelfriends.R

class BookAdapter(
    private val books: List<Book>,
    private val onBookClick: (Book) -> Unit
) : RecyclerView.Adapter<BookAdapter.BookViewHolder>() {

    override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): BookViewHolder {
        val view = LayoutInflater.from(parent.context).inflate(R.layout.item_book, parent, false)
        return BookViewHolder(view)
    }

    override fun onBindViewHolder(holder: BookViewHolder, position: Int) {
        val book = books[position]
        holder.bookTitle.text = book.name
        holder.bookDescription.text = book.description

        Log.d("Glide", "Context available: ${holder.itemView.context}")
        Log.d("Glide", "Loading image from URI: ${book.image}")

        // Verwende Glide, um das Bild zu laden
        Glide.with(holder.itemView.context)
            .load(Uri.parse(book.image))
            .placeholder(R.drawable.ic_launcher_foreground)
            .error(R.drawable.ic_launcher_foreground)
            .into(holder.bookImage)

        holder.itemView.setOnClickListener {
            onBookClick(book)
        }
    }

    override fun getItemCount(): Int {
        return books.size
    }

    // ViewHolder für jedes Buch
    class BookViewHolder(view: android.view.View) : RecyclerView.ViewHolder(view) {
        val bookTitle: TextView = view.findViewById(R.id.tvRecViewBookTitle)
        val bookDescription: TextView = view.findViewById(R.id.tvRecViewBookDescription)
        val bookImage: ImageView = view.findViewById(R.id.ivRecViewBookImage)
    }

}

package com.example.travelfriends.ui.fragments

import android.os.Bundle

import com.example.travelfriends.data.Question


class LibraryShowBooksFragment : Fragment() {


    private lateinit var appViewModel: AppViewModel
    private lateinit var recyclerView: RecyclerView
    private lateinit var bookAdapter: BookAdapter

    override fun onCreateView(
        inflater: LayoutInflater, container: ViewGroup?,
        savedInstanceState: Bundle?
    ): View? {
        // Inflate the layout for this fragment
        val view = inflater.inflate(R.layout.fragment_library_show_books, container, false)

        recyclerView = view.findViewById(R.id.recyclerViewBooks)
        recyclerView.layoutManager = LinearLayoutManager(requireContext())

        appViewModel = ViewModelProvider(requireActivity())[AppViewModel::class.java]

        //Alle Bücher laden
        appViewModel.getAllBooks()

        // Lade alle Bücher und setze den Adapter
        appViewModel.allBooks.observe(viewLifecycleOwner) { books ->
            recyclerView.adapter = BookAdapter(books) { book ->
                // Navigiere zu BookDetailsFragment mit dem Buch als Argument
                val action = LibraryShowBooksFragmentDirections.actionLibraryShowBooksFragmentToBookDetailsFragment(book.bookId)
                findNavController().navigate(action)
            }
        }

        return view
    }

}

Here it doesnt work:

        return inflater.inflate(R.layout.fragment_book_details, container, false)
    }

    override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
        super.onViewCreated(view, savedInstanceState)
        appViewModel = ViewModelProvider(requireActivity())[AppViewModel::class.java]
        imageBook = view.findViewById(R.id.imageBook)
        bookTitle = view.findViewById(R.id.tvBookDetailsTitle)

        val bookId = args.bookId


        // Buchdaten beobachten und anzeigen
        appViewModel.getBookDetailsById(bookId)

        appViewModel.bookDetails.observe(viewLifecycleOwner) { book ->
            if (isAdded && book != null) {
                bookTitle.text = book.name

                val imageUri = book.image
                Log.d("Glide", "uri: ${imageUri}")
                Log.d("Glide", "context: ${context}")
                if (imageUri.isNotEmpty()) {
                    context?.let {
                        Glide.with(it)
                            .load(imageUri)
                            .placeholder(R.drawable.ic_launcher_foreground)
                            .error(R.drawable.ic_launcher_foreground)
                            .into(imageBook)
                    }
                } else {
                    imageBook.setImageResource(R.drawable.ic_launcher_foreground)
                }
            }


        }
    }
}

Here are the Log-Messages (its the same context and uri)
