That's an extremely niche set of requirements, largely because interoperating with C++ is, well, a nightmare, and partly because "fast code" means something very different to C++ devs than to most devs who use managed runtimes.
Also, there are different definitions of "safe". Rust takes a very C++ style view: it's "safe" in the sense that UB requires either a compiler bug or an explicit opt-in to something unsafe.
For other definitions of "fast" and "safe", sure, most garbage collected languages count. Java, C#, and Go are "fast enough" for most application code, and they mostly guarantee that errors will result in crashes rather than UB. Zig is as fast as C/C++/Rust (and integrates much more easily with C than any other language except C++) and has a very different approach to safety (mostly runtime checks in debug mode that are not included in release mode).
