Swapping Wormhole pos USDC to native USDC on Avalanche is not possible. This is because the token has been bridged, meaning it has no liquidity or utility. To bridge this token back, you need to paste the token contract address (which can be found in your wallet) into the Wormhole “select a token” search field. After doing this, you can find a comprehensive overview of liquid markets in the Wormhole Network documentation. However, it is not possible to swap the token directly to native USDC on Avalanche.
