Code:
30: OP_SEQUENCE_0x30: type tag indicating SEQUENCE, begin sigscript
45: OP_LENGTH_0x45: length of R + S
02: OP_INT_0x02: type tag INTEGER indicating length

02
21: unknown opcode
I can see a double zero is there, so the length of the R-Value should be 21hex, 33 bytes decimal. In you case it would end with "02".
However: the 02 should be the type tag indicating length for S-Value, and 21 the length for your S-Value (which it is...).
I just added a "DD" into the end of the R-Value, then it decodes correctly:
Code:

45: OP_LENGTH_0x45: length of R + S
02: OP_INT_0x02: type tag INTEGER indicating length

01: OP_SIGHASHALL: this terminates the ECDSA signature (ASN1-DER structure)
So I guess the library you are using is not assembling the signatures correctly. What are you using?
