This is a follow-up of #924. The same crash can happen even with format, as it will result in a call to put_time(which will make call to functions like _Strftime):

#include<format>
#include<iostream>
#include<chrono>
int main() {
	using namespace std::chrono;
	try {
		sys_time<seconds> t{seconds(335303598060)};
		std::cout << std::format("{:%c}", t);
	}
	catch (std::exception& e) {
		std::cout << e.what();// unreacheable.
	}
	return 0;
}

Unhandled exception at 0x00007FF80ACA1208 (ucrtbase.dll) in test.exe:
An invalid parameter was passed to a function that considers invalid parameters fatal.

Please consider doing some investigations for strftime series. The crash-on-failed-check behavior interacts really poorly with C++.
