"a project right now where I literally can’t attach a debugger or run locally" ... this is exactly where record-and-replay tools like rr can change the game. You can (potentially) run that code under rr on the remote machine --- without interrupting it, which is often problematic --- then upload the recording somewhere (e.g. Pernosco) for debugging.
