This is yet another attempt to get the injector stable. This should fix the issue where client version was being missed. It also should fix some exceptions. No injector issues have been reported so far, so if you have issues, join the discord.
I also added support for 1.19.3, although it's experimental and not extensively tested. Please note that while this supports 1.19.3, I have not added support for the experimental datapack. Using the experimental datapack will result in undefined behavior.
