take a look at the vanilla logic: LivingEntity#isDamageSourceBlocked and LivingEntity#isBlocking

you need add it to the Item.Properties of your Item

Try without Better Loading Screen. if the game still crash, post debug log, on CurseForge you need to enable the debug log in the settings

you can add [Solved] to the start of title, of this thread

you can modify the Ore generation via the BiomeLoadingEvent, remove the PlacedFeature of the vanilla Ore and add then your new PlacedFeature to the BiomeGenerationSettingsBuilder

there is a debug log, if you use CurseForge you need to enable the debug log in the settings

post debug log

you could try to disable the Biomes O Plenty Nether Biomes via the config, if this won't work, then the mods are not compatible

unfortunately this is hardcoded in vanilla via private static methods in the CrossbowItem class, the best way would be to copy these methods and edit them in your Item class the methods you need to copy are: CrossbowItem.getArrow, CrossbowItem.shootProjectile and CrossbowItem.performShooting then you be able to modify the AbstractArrow in your custom getArrow method, you can set the Arrow damage via AbstractArrow#setBaseDamage after that you also need to override #use, you can copy the logic from vanilla but note you need to call you custom performShooting there you will probably need a few AT's if you don't want to copy the complete vanilla logic from the Crossbow, since there are several private static methods that you have to call from your custom methods (i told you above)

Problem with U Team Core. Make sure you are using the latest version. If the Mod is already up to date, report this bug to the Mod author.

the problem is cause by java, since the version is not compatible with forge

there is no tag for the Nether Star, you need to use the item in your recipe

if there is then no other Mod which cause a crash then yes
