What if you try playing without your BDCraft resource pack? Are you using the super ultra mega one with the highest resolution? Try it with vanilla, or a smaller res resource pack and see if it still crashes. edit: also, use F3 to make sure it is using your Nvidia card, and not the built in Ryzen graphics.

I think you might be in the wrong place looking for help with this. Or you posted the wrong crash? Does not appear to be any forge being used here, and it's a snapshot version of Minecraft, not a release version.

Make sure you scan through the entire log, you will (usually) eventually find something that makes some kind of sense.

Not really sure, but I think the minecraft forums have a section for modding, you could see if they support old versions there.

The @Override notation is used when overriding a method defined in a parent class, to either replace or add additional functionality.

Please post logs as described in the EAQ, unfortunately pictures (even when they have error messages) do not have enough information to figure out what the problem is.
