Emulator Issues #13516

Unhandled exception from formatted timestamp on savestate file scanning
0%
Description
What's the problem? Describe what went wrong.
As the title claims, there appears to be an odd situation going on, for me anyway, where Dolphin will "crash and burn" when attempting to format a file timestamp from a savestate of any game.
What steps will reproduce the problem?
I have no idea if anyone else is affected, but I can consistently reproduce the problem on my side. If a game I attempt to boot has any savestate file, it will crash the emulator immediately. If not, I have to create a savestate first (which works fine), then it's anyone's guess what's going to trigger it again. Even the quit dialog after pressing Esc has done it.
Is the issue present in the latest development version? For future reference, please also write down the version number of the latest development version.
I compiled the latest source code via MSVC to sound things out. Definitely present. The "oldest" version I tried where the issue isn't present was directly from a beta build download, 5.0-20347, from 4 and a half months ago. That version runs fine, but its immediate next beta build (5.0-21088) does have the same issue as current. 800+ revisions isn't a small window, but it should narrow things down.
What are your PC specifications? (CPU, GPU, Operating System, more)
Running on Windows 11, Version 10.0.22631, Build 22631
Ryzen 5, 5600
Nvidia RTX 2080
The hardware specs don't really make a difference here.
Is there anything else that can help developers narrow down the issue? (e.g. logs, screenshots,
configuration files, savefiles, savestates)
Got a stack trace. Timestamp's fine according to Jos, so the issue occurs somewhere in the format call's inner workings.

If you replace line 291 of Core/Core/State.cpp with the following, what values do you get?
auto loc = std::locale{""}; auto name = loc.name(); auto time_flags = loc.time; NOTICE_LOG_FMT(COMMON, "Locale name: {}", name); NOTICE_LOG_FMT(COMMON, "Locale time flags: {}", time_flags); // fmt is locale agnostic by default, so explicitly use current locale. return fmt::format(loc, "{:%x %X}", *local_time);
