Incorrectly Throwing Error for Channel Deletion

Summary

Incorrectly Throwing Error for Channel Deletion

Reproduction Steps

Copy reproducible code below, to a Cog listener. Replace the constants with your own, then join the channel. When you leave the channel, observe that an exception is thrown.

Minimal Reproducible Code

@commands.Cog.listener()
    async def on_voice_state_update(self, member: discord.Member, before, after):
        joined_channel_name = after.channel.name if after.channel else None
        
        try: 
            if before.channel and before.channel.id in self.created_channels:
                if len(before.channel.members) == 0:
                    await before.channel.delete()
                    del self.created_channels[before.channel.id]
                    return
            
            if joined_channel_name == CREATE_VC_CHANNEL_NAME:
                new_channel = await member.guild.create_voice_channel(
                    name=f"{member.display_name}'s Channel",
                    category=after.channel.category,
                    position=after.channel.position + 1
                )
            
                await member.move_to(new_channel)
                self.created_channels[new_channel.id] = new_channel

                view = discord.ui.View()
                view.add_item(ManageChannelButton())

                await new_channel.send(
                    f"Welcome to your new channel, {member.mention}!",
                    view=view
                )
                
        except Exception as e:
            print(f"[create_vc] An error occurred: {e}")

Expected Results

I expected it to delete the channel, when no members are connected, without throwing an error.

Actual Results

Channel was deleted, error thrown.

Unable to reproduce using the following code:

@commands.Cog.listener()
    async def on_voice_state_update(self, member: discord.Member, before, after):
        joined_channel_name = after.channel.name if after.channel else None

        try:
            if before.channel and before.channel.id in self.created_channels:
                if len(before.channel.members) == 0:
                    await before.channel.delete()
                    del self.created_channels[before.channel.id]
                    return

            if joined_channel_name == "vctest":
                new_channel = await member.guild.create_voice_channel(
                    name=f"{member.display_name}'s Channel",
                    category=after.channel.category,
                    position=after.channel.position + 1
                )

                await member.move_to(new_channel)
                self.created_channels[new_channel.id] = new_channel

                #view = discord.ui.View()
                #view.add_item(ManageChannelButton())

                await new_channel.send(
                    f"Welcome to your new channel, {member.mention}!")#,
                    #view=view
                #)

        except Exception as e:
            print(f"[create_vc] An error occurred: {e}")

I suspect you have an issue in your view. As @pythonmcpi said, please include the traceback.
