This error seems to be from EDR, it happens when this plugin calls debug_tracett on hardhat_provider. It is because some chains have introduced new transaction types that do not exist on Ethereum L1 and hardhat's EDR only implements L1s transaction types AFAIK.

A potential patch on hardhat could be to ignore transactions with unsupported types and exec the block anyway.

I've ran into this on Unichain as well. Will be happy to send patch PR if you can guide me where it should be implemented
