I think so (that the liq needs to be in ETH) because while creating the contract, you created a pair for WETH (0x3cdf83b357d6736988f333d0cda850986e61f52e) https://etherscan.io/tx/0x64cdfadf6b6eafb9c67907287167db18b4470623ac3fb3c75530588068def45d#internal
So maybe remove the USDC liq, convert it to ETH and addliq to the aforementioned pair.
