Work in a big tech company "MAMMA" as is called today, can't tell which one due to and NDA, a LOT of our codebase still Objc and there is no plans to move a single line, so rest assure Objc will be very alive at least in big tech projects, now for startups or some other projects Swift is ramping up quickly, but I worked in another company that had Objc code base and eventually we started moving to Swift, but it was always a combination of both worlds. Objc still as powerful as C/C++ today.

I have the same issue as well, started with Xcode14 even with Monterey. I did a clean re install and it it not working. A friend from work is having the same issue. Seems it is only related to Apple Silicon Macs.
