I have a similar problem.
asn1tools.codecs.ber.DecodeTagError when using two "SEQUENCE OF" in "CHOICE"
My ASN.1 file:
A DEFINITIONS::=BEGIN
B::=CHOICE{
c SEQUENCE OF INTEGER,
d SEQUENCE OF IA5String
}
END
My python code:
import asn1tools
asn_file = asn1tools.compile_files('./test.asn',codec='ber')
encoded = asn_file.encode('B', ('c', [1]))
print(hex(int.from_bytes(encoded, byteorder='big')))
decoded = asn_file.decode('B', encoded)
print(decoded)
Output:

asn1tools.codecs.ber.DecodeTagError: B.d: Expected IA5String with tag '16', but got '02'. (At offset: 2)
from asn1tools.
The OSS Nokalva playground gives a compile error: line 4 (A): A0100E: Duplicate tag in type B: element 'c' (line 3) and element 'd' (line 4).
asn1tools
should probably give an compile error as well, but I guess there is a bug.
