比特币测试网原生SegWit交易提交失败（RPC错误-26）求助

• 提交原生SegWit交易到比特币测试网时失败，触发RPC错误-26，源码定义该错误为：
  RPC_VERIFY_REJECTED = -26, //!< Transaction or block was rejected by network rules
• 交易通过PSBT创建，完成所有输入签名、最终化后提取十六进制字符串，提交至https://blockstream.info/testnet/api/tx
• 签名后的交易十六进制：

020000000001024aa98a288909cd44fa7abfb3418cacec2978fd41270b7d6917f0b8fecf92d8e80100000000ffffffff8e4777141e8f81b56237980e0380a79432ec3b82862deb34d5ff3efc701b01f80100000000ffffffff01e80300000000000016001472b11f9b893032a316151b457d51614d5be4c2120247304402200e00725946a9d176649d247644626c75d33c2e08566fb735ef036b25d54b9e15022035da9eb7ed15ae036bea2cb01ad0f2d0291c5612abd039fa84b0c4e11265352b0121036123e7fc019fd0883f5957bd47ce1273d28ed950407c1a6686e86d4d3b00405302483045022100a72f331387f666b357fe96eab028b64dcf542d7b07ac326527ab3e4da7d57233022024944bcd1b4eea97657e145f79cbaf819681409a219224fe696bcdf1b8fd39f50121036123e7fc019fd0883f5957bd47ce1273d28ed950407c1a6686e86d4d3b00405300000000

• 已使用交易解码工具验证过，个人认为原生SegWit格式符合规范，但提交仍失败，求排查方向。
