Research direction
Reproduce the error by opening a binary, selecting a High Level IL rendered view, and clicking the outer braces of a function definition in Pseudo-C, Pseudo Objective-C, or Pseudo Rust. Start at HighLevelLanguageRepresentationFunctionGraph and inspect how the brace click resolves HighLevelIL tokens; done means those clicks no longer report an invalid token or the maximum instrIndex.
