Your argument does not work as a praise for Rust because the bugs in any program are caused by programmer errors, except the very rare cases when there are bugs in the compiler tool chain, which are caused by errors of other programmers.
The bugs in a C or C++ program are also caused by programmer errors, they are not inherent to C/C++. It is rather trivial to write C/C++ carefully, in order to make impossible any access outside bounds, numeric overflow, use-after-free, etc.
The problem is that many programmers are careless, especially when they might be pressed by tight time schedules, so they make some of these mistakes. For the mass production of software, it is good to use more strict programming languages, including Rust, where the compiler catches as many errors as possible, instead of relying on better programmers.

The actual bug had nothing to do with rust, yet rust is specifically brought up here.
(grandparent comment): "Rust isn’t a panacea, it’s a programming language. It’s ok that it’s flawed, all languages are."
No Rust programmer thinks it's a panacea! Rust has never advertised itself this way.
And then, it turned out to not really be any better than exceptions.
Most Rust evangelism is like this. "In Rust you do X and this makes your code have fewer bugs!" Well no it doesn't. Manually propagating exceptions still makes the program crash and requires more typing, and doesn't emit a stack trace.
