Incorrect reserialization on presence sync

[outmaneuver]

Summary

assets breaking

Reproduction Steps

pass a streaming type activity using change_presence method with assets url name and details, go on discord edit your custom status through the profile no need to even touch the selfbot just use it to run the presence, wait a bit and your activity's assets are now gone but at least the activity will remain (sometimes it does disappear probably discord's fault though)

I'm including my method for creating the presence below, other activities do work fine (i think, haven't tested extensively) it's just the streaming one for some odd reason P.S ignore the custom_status method yes it happens when i use it too but it also happens without using it so it's quite irrelevant

Code

async def update_presence(self, status=None):
        try:
            config = self.load_config()
            presence_config = config.get('presence', {})
            
            # Determine status
            status_str = status.name.lower() if status else presence_config.get('status', 'dnd').lower()
            status = getattr(discord.Status, status_str, discord.Status.dnd)
            
            activities = []
    
            # Add rich presence if enabled
            if presence_config.get('enabled') and presence_config.get('application_id'):
                app_id = presence_config['application_id']
                await self.fetch_application_assets(app_id)


                activity_type = str(presence_config.get('type', 'playing')).lower()
                activity_kwargs = {
                    'application_id': presence_config['application_id'],
                    'type': self.ACTIVITY_TYPES.get(activity_type.lower()) or self.ACTIVITY_TYPES.get(activity_type) or discord.ActivityType.playing,
                    'name': presence_config.get('name', ''),
                    # don't pass if streaming type
                    'state': presence_config.get('state') if activity_type not in ['streaming', '1'] else None,
                    'details': presence_config.get('details'),
                }

                # Only add URL if type is streaming (either by name or number)
                if (activity_type == 'streaming' or activity_type == '1') and presence_config.get('url'):

                # Add timestamps

                # Handle buttons
                buttons = []

                    activity_kwargs['party'] = party

                    if emoji := custom_status.get('emoji'):
                        custom_activity.emoji = discord.PartialEmoji.from_dict(emoji)
                    activities.append(custom_activity)
    
            # Update presence with all activities
            await self.bot.change_presence(status=status, activities=activities)
    
        except Exception as e:
            print(f"Error updating presence: {e}")
            import traceback
            traceback.print_exc()

Expected Results

the assets not to disappear from the activity lmao?

Actual Results

the activity continues running with broken assets

and just in case you didn't understand that break happens when i play with this little fella :)
