Describe the bug
Unable to create an instance of PacketLoginInStart packet using the latest dev build (https://ci.dmulloy2.net/job/ProtocolLib/602/). Works perfectly when using stable version (4.8.0).
I think the problem is because it is using the default WrappedGameProfile, but I didn't find any way to set it when creating the PacketContainer.
To Reproduce
Try to create an instance of the PacketLoginInStart packet, like the code in the Additional context section
Expected behavior
Being able to create the PacketLoginInStart instance without errors.
Version Info
Provide your ProtocolLib install info with /protocol dump through pastebin.

I'm using the code below:
PacketContainer startPacket = new PacketContainer(START); // <---------- ⚠️ STACKTRACE LINE ⚠️
startPacket.getGameProfiles().write(0, originalPacket.getGameProfiles().read(0));
