Substrate Node Template does not start

Question

I followed the tutorial on https://docs.substrate.io/tutorials/build-a-blockchain/build-local-blockchain/ exactly, but after building the node template (https://github.com/substrate-developer-hub/substrate-node-template) and trying to run it with ./target/release/node-template --dev I get the following error message:

Error: Service(Client(VersionInvalid("cannot deserialize module: UnknownOpcode(192)")))

Answer 1

This issue happens in recent rust nightly builds, try downgrading to nightly-2023-03-14

More info:

• https://github.com/paritytech/substrate/issues/13636
• cannot run substrate on a fresh macbook m2

Once you downgrade the nightly toolchain, you will have to build the project again.
