Other info

I was using unstable feature of tokio and this was my .cargo/config.toml

Note the comments are intentional. I already commented out the lines about mold a few days ago before I hit the ICE so may or may not be related.

[build]
rustflags = ["--cfg", "tokio_unstable"]

# [target.x86_64-unknown-linux-gnu]
