To check my understanding of the signing and verifying course of i attempted to confirm some random Bitcoin transactions by hand. Sadly i obtained caught with a P2WSH transaction, i select the next transaction with Hash c53b99c9fdba60fd47c6026177d3f6e1ed6d3abde8f433364619aa7d437dad26
With the uncooked transaction:

I can deserialize this to:

Now i attempt to compute the MessageHash that will get signed:
with:
hashPrevouts = sha256²(2198e5bc0860a4fcf420e2b909fce47e746357457b060c63571e12bd84fec4a701000000)
hashSequence = sha256²(ffffffff)
hashOutputs = sha256²(20120a0000000000a91417b9a9afddaae527d25788bce2202563d4ab0d058784ea1100000000000020701a8d401c84fb13e6baf169d59684e17abd9fa216c8cc5b9fc63d622ff8c58d)

This can give me the MessageHash = 8560e61d0167f784d0cdaf9d45ba0e1be752e94d30a34339d976b01e50f0e366
But when i attempt to confirm this MessageHash with the primary Signature(473044022014cd600863ad3c9f6802383fe814a693a77144117cf7694f63b558b8c02d801c02201c3ad9901f659742668caf770f3d7f89a3633f9ccd2bfdd6a7c6f7529fe7b43101), which has R = 14cd600863ad3c9f6802383fe814a693a77144117cf7694f63b558b8c02d801c and S = 1c3ad9901f659742668caf770f3d7f89a3633f9ccd2bfdd6a7c6f7529fe7b431 in opposition to any of the three PubKeys in Witness 0 3, i all the time get the the Signature just isn’t legitimate.
Can somebody inform me the place i obtained unsuitable ?
