  if (!guild) return;
  if (guild) {
    guild.channels.cache.filter(kanal => kanal.deleted !== true).forEach(channel => {
      let permissionss = {};
      let sayi = Number(0);
      channel.PermissionOverwriteManager.forEach((perm) => {
        let thisPermOverwrites = {};
        perm.allow.toArray().forEach(p => {
          thisPermOverwrites[p] = true;
        });
        perm.deny.toArray().forEach(p => {
          thisPermOverwrites[p] = false;
        });
        permissionss[sayi] = {permission: perm.id == null ? guild.id : perm.id, thisPermOverwrites};
        sayi++;

error Channel#deleted is deprecated, (Use node --trace-deprecation ... to show where the warning was created) TypeError: channel.permissionOverwrites.forEach is not a function

Discord js upgrade error v12 to v13 ı need help

Basically the function channel.deleted has been removed from discord.js and you can't use it anymore. Full article on this: https://github.com/discordjs/discord.js/issues/7091. You can simply remove the filter in the channel cache to solve the problem. It also appears that you haven't created a permissionOveriteManager, and it's spelled wrong. The code would then look like the following:

function kanalbackup() {
  let guild = client.guilds.cache.get(ayarlar.guildID);
  if (!guild) return;
  if (guild) {
    guild.channels.cache.forEach(channel => {
      let permissionss = {};
      let sayi = Number(0);
      channel.permissionOverwriteManager.create().forEach((perm) => {
        let thisPermOverwrites = {};
        perm.allow.toArray().forEach(p => {
          thisPermOverwrites[p] = true;
        });
        perm.deny.toArray().forEach(p => {
          thisPermOverwrites[p] = false;
        });
        permissionss[sayi] = {permission: perm.id == null ? guild.id : perm.id, thisPermOverwrites};
        sayi++;
      })
