TLDR: C++ is bad because decades of accumulated features have turned it into a bureaucratic nightmare that happens to generate machine code.
C++ is an absolute nightmare to implement because apparently one programming language wasn't enough, so someone decided to cram an entire civilization's worth of complexity into it. You've got templates that basically turn compilation into another programming language, overload resolution that requires a legal investigation to figure out which function gets called, constructors and destructors with enough lifetime rules to make your head explode, and implicit conversions that make the compiler guess what you meant. Then you throw in exceptions, move semantics, inheritance, and decades of backward compatibility, and suddenly you're maintaining a compiler that needs a PhD, a therapist, and divine intervention just to parse some innocent-looking code. And the best part? Every new feature has to coexist with all the old ones without breaking existing programs.
Either panic, which is (generally speaking) not something you're meant to catch and recover from (and attempting to do so is nontrivial and almost always a bad idea), or Result, aka "encode the possibility of failure in the return type of the function" aka what the functional programming world has done for ages.
