Its definitley tricky this. TISGetInputSourceProperty is causing the seg fault. Here is some interesting code..

Note if we change that byte code returned its all returning with None as the input types

import ctypes
import objc
from Foundation import NSDictionary

Carbon = ctypes.CDLL('/System/Library/Frameworks/Carbon.framework/Carbon')

# Define the type of the TISCreateInputSourceList function
Carbon.TISCreateInputSourceList.restype = ctypes.c_void_p
Carbon.TISCreateInputSourceList.argtypes = [ctypes.c_void_p, ctypes.c_bool]

# Define the type of the TISGetInputSourceProperty function
Carbon.TISGetInputSourceProperty.restype = ctypes.c_void_p
Carbon.TISGetInputSourceProperty.argtypes = [ctypes.c_void_p, ctypes.c_void_p]

# Define the kTISPropertyInputSourceID constant
# Define the kTISPropertyInputSourceID constant
# Define the kTISPropertyInputSourceID constant
kTISPropertyInputSourceID = ctypes.c_void_p.in_dll(Carbon, 'kTISPropertyInputSourceID')
kTISPropertyInputSourceID = objc.objc_object(c_void_p=kTISPropertyInputSourceID)
# Create a list of all input sources
input_sources = Carbon.TISCreateInputSourceList(None, False)

from ctypes import CFUNCTYPE, c_void_p, c_bool

# Define the CFArrayGetCount function
CFArrayGetCount = CFUNCTYPE(c_void_p, c_void_p)(('CFArrayGetCount', Carbon))

# Define the CFArrayGetValueAtIndex function
CFArrayGetValueAtIndex = CFUNCTYPE(c_void_p, c_void_p, c_void_p)(('CFArrayGetValueAtIndex', Carbon))

# Create a list of all input sources
input_sources = Carbon.TISCreateInputSourceList(None, False)

# Get the number of input sources
num_sources = CFArrayGetCount(input_sources)

# Define the kTISPropertyInputSourceID constant
kTISPropertyInputSourceID = ctypes.c_void_p.in_dll(Carbon, 'kTISPropertyInputSourceID')

# Print details about each input source
for i in range(num_sources):
    source = CFArrayGetValueAtIndex(input_sources, i)
    source_id_ptr = Carbon.TISGetInputSourceProperty(source, kTISPropertyInputSourceID)
    if source_id_ptr is not None:
        source_id = ctypes.c_char_p(source_id_ptr).value
        print(f"Input source {i}: {source_id}")
