I am trying to make a password manager in python and ahve ran into a issue, i cannot load a different dll once i have loaded one type of dll, in this example i have loaded a dll and am trying to decrypt encrypted password data and it works fine until i load another DIFFERENT nss3.dll file at which point it gives me an error:

“The procedure entry point HeapAlloc could not be located in the dynamic link library C:Program FilesWaterfoxnss3.dll”

I only get this error after loading multiple nss3.dll files for example:

def DecryptFirefoxBased(Type,EncryptedPassword):
    EncryptedPassword = base64.b64decode(EncryptedPassword)
    nss3 = ctypes.CDLL(Paths[Type][1])
    nss_init = nss3.NSS_Init
    nss_init.argtypes = [ctypes.c_char_p]
    nss_init.restype = ctypes.c_int
    nss_init(ProfileDirectory.encode())
    pk11_sdr_decrypt = nss3.PK11SDR_Decrypt
    pk11_sdr_decrypt.argtypes = [ctypes.POINTER(SecItem), ctypes.POINTER(SecItem), ctypes.c_int]
    pk11_sdr_decrypt.restype = ctypes.c_int
    EncryptedItem = SecItem()
    EncryptedItem.data = ctypes.create_string_buffer(EncryptedPassword)
    EncryptedItem.len = len(EncryptedPassword)
    DecryptedItem = SecItem()
    decrypted_buffer = ctypes.create_string_buffer(len(EncryptedPassword))
    DecryptedItem.data = ctypes.cast(decrypted_buffer, ctypes.POINTER(ctypes.c_char))
    DecryptedItem.len = len(EncryptedPassword)
    ret = pk11_sdr_decrypt(ctypes.byref(EncryptedItem), ctypes.byref(DecryptedItem), 0)
    if ret != 0:
        input("PK11SDR_Decrypt failed")
    return ctypes.string_at(DecryptedItem.data, DecryptedItem.len).decode()

In the reference above that is being called more than once with a different dll being loaded each time on the second time it breaks, that’s really all information i can give, if anybody knows why i get this error please help me out or hint to why this is happening cus its really starting to irritate me.
