Description
Code
I was working on #91018, a follow up for #89933, and was adding let_else to rustc_mir_build when I encountered the ICE.
The code is available in my local rustc fork on the let_else_ice branch. I've minimized it to the single invocation that causes the ICE.
Error output
thread 'rustc' panicked at 'called `Option::unwrap()` on a `None` value', compiler/rustc_borrowck/src/diagnostics/mutability_errors.rs:53:62
