I believe this is because of the Petersburg hardfork on Rinkeby at that block. You need 2.4.6 https://github.com/paritytech/parity-ethereum/releases/tag/v2.4.6

Make sure you backup your chain first just in case.

@sicute I'll close this issue now in the hope that @AC0DEM0NK3Y 's advice was useful to you. Feel free to re-open if not.
