Reuse of Nonce R and Private Key Recovery

Hello,

I noticed that a P2PKH address d1 has reused the same nonce R = 532afmore twice, while the P2PKH address d2 has used R = 532afmore only once.

Since reusing the same R in two different ECDSA signatures allows private key extraction, is it possible to recover the private key of d2, given that it used R = 532afmore only once?

Thanks for your insights!
