Can two bitcoin transactions from a Segwit address (p2sh-p2wpkh) have a reused R value?
Segwit does not use a different signature algorithm nor does it change any of the properties of a ECDSA signature. Thus if you find transactions that involve the same public keys and the same R value, then yes, the private key for that public key is revealed.

However, what you are looking at is not the R value. In fact, you are not even looking at the signature. Rather you are looking at part of the redeemScript. 145d3cbed9f338b82667f410340fcb9bf401c7e837e9f4539b915fb8bced is part of the hash of the witnessScript, not part of a signature.

The address 3AQ4kUjQaDjCjmDh2ojKEHjUKTSi52UUqD is a P2SH-P2WSH address. This means that it maps to a Pay to Script Hash (P2SH) output script, which has a redeemScript for a Pay to Witness Script Hash (P2WSH) script. The P2WSH script contains the hash of the witnessScript, which, in this case, is a multisig script.
