Same error here, but with aes_gcm library.

error: internal compiler error: compiler/rustc_infer/src/infer/error_reporting/need_type_info.rs:856:33: unexpected path: def=aes_gcm::aead::generic_array::GenericArray substs=[_, _] path=Path { span: src/services/encryption.rs:53:25: 53:30 (#0), res: Def(TyAlias, DefId(180:97 ~ aes_gcm[7ab9]::Nonce)), segments: [PathSegment { ident: Nonce#0, hir_id: Some(HirId { owner: DefId(0:223 ~ easylink[c894]::services::encryption::encode), local_id: 61 }), res: Some(Err), args: None, infer_args: true }] }

Could have been introduced by #89862.

It seems that this issue may be caused by a bug in your code, you can try reverting to nightly-2022-06-02, fixing the errors, then setting it back to latest nightly.

I run into the same problem
