fresh install on new(to me) setup. using WSL ubuntu. do foundryup, everything is good. start an anvil local chain, it spins up nicely.

Genesis Timestamp
==================

Listening on 127.0.0.1:8545
eth_blockNumber
Anvil is ready on port 8545.

then I go to run my deploy script with forge script script/Deploy.s.sol --broadcast --fork-url http://localhost:8545

get strange error I have never seen before when running this same script against local anvil on a different computer I have.

Error:
Could not instantiate forked environment with fork url: http://localhost:8545

Context:
- Failed to get block for block number: 12
latest block number: 12

I am not sure what an "archive node" is, and didn't see any mention of it on https://book.getfoundry.sh/reference/anvil/
tried explicitly passing various --fork-block-number, which didn't really change much. tried googling, and looked through the issues here. I see nothing. tried installing an earlier commit of foundry with foundryup -C 63fff3510408b552f11efb8196f48cfe6c1da664 and got same results. tried logging within my Deploy.s.sol, but none of the logs were ever hit, which leads me to believe it is happening at some earlier layer of code I didn't write. perhaps something in here?

import { Script } from "forge-std/Script.sol";

I'm happy to provide more information if needed.

more digging seems to show that it's from anvil being started with --load-state option which seems to fail on the particular serialized state I'm using

bump, I think related to this: #7502

Marking as resolved by #7502, unrelated to forge.

Feel free to re-open if you run into this again.

Met the same error using anvil 0.2.0 (7f0f5b4 2024-08-08T00:19:27.666925503Z).
