When using npx hardhat compile --verbose in a hardhat repo that uses IState I get:

Please report this at https://zpl.in/upgrades/report. If possible, include the source code for the contracts mentioned in the errors above.

This is how it is used in contract:
import {StateV2} from "@iden3/contracts/state/StateV2.sol";

Hi, @joelamouche. As a quick fix you can try to install native the solc binary. It works with the binary from my side.
