thread 'rustc' panicked at 'called Option::unwrap() on a None value',

[brettman]

Going through the blockchain tutorial here:
https://www.youtube.com/playlist?list=PLwnSaD6BDfXL0RiKT_5nOIdxTxZWpPtAv

Haven't had any issues for a couple days off an on just plowing through the tutorial videos. Suddenly the complier starts panicking. Not sure what's causing the error but you can the code is here:
https://github.com/brettman/blockchain-rust

As far as I can tell it's pretty much exactly what they have in the tutorial repo which builds fine still for me.

error: internal compiler error: unexpected panic

note: the compiler unexpectedly panicked. this is a bug.

note: we would appreciate a bug report: https://github.com/rust-lang/rust/issues/new?labels=C-bug%2C+I-ICE%2C+T-compiler&template=ice.md

note: rustc 1.57.0 (f1edd04 2021-11-29) running on x86_64-apple-darwin

note: compiler flags: -C embed-bitcode=no -C split-debuginfo=unpacked -C debuginfo=2 -C incremental --crate-type lib

note: some of the compiler flags provided by cargo are hidden

This should be fixed in the latest nightly
