Compiling error help [Solved]

I'm trying to make a custom tree spawn as a structure, but can't make it so that it only generates if it has enough room. Can you tell me what causes the error, or a better way to do it without the error?

Edit: It works after i removed the false statement from:

if ((world.getBlockState(new BlockPos(x + 2, y - 1, z + 2))).getBlock() == Blocks.SCULK || (world.getBlockState(new BlockPos(x + 2, y - 1, z + 2))).getBlock() == Blocks.DEEPSLATE 
                || (world.getBlockState(new BlockPos(x + 2, y - 1, z + 2))).getBlock() == Blocks.STONE) { 
            return true; 
        } else { 
            return false;
