called Option::unwrap() on a None value, compiler/rustc_hir/src/definitions.rs:452

Code

I could not reproduce this error after cargo clean, so I can't create a minimum reproduction of the bug.
I can, however, provide the complete source, with /target/. I have zipped the directory while it's still reproducing the error.
I don't want to share my code unless necessary, so if this is not a duplicated error, or some sort of corruption from my end, let me know where to upload it, and I'll post the link here.
Here's the exact location where the unwrap happens in rustc:

[giraffate]

Thanks for the report!

This might be duplicate as rust-lang/rust#89260. And it seems to be rustc issue, not Clippy.

[AlexApps99]

I'll close this in favor of rust-lang/rust#89260
