Setting short date format in windows makes WinNut crash

[HotelAlpha4]

I have my short date set to yyyy-MM-dd as it removes the confusion of the default dd/MM/yyyy format given occasional reversed date formats. WinNut is confirmed to crash with any short date format that starts with a year. The day/month/year formats all work, as does the month/date/year formats, but they leave a developer guessing the meaning of any short date. I am hoping this is a quick fix, but for the meantime, dd/MMM/yyyy works fine and achieves a similar result.

Could you please provide a log and/or exact error message of the crash, along with version of WinNUT?

Hello,
I guess I have a similar issue.
I've recently changed the regional format on my computer (from Italian to US) and WinNUT always crashes at the startup with this error log:

Exception type: System.FormatException
Exception message: String was not recognized as a valid DateTime.
Exception stack trace:

The date has changed from dd/mm/yyyy to mm/dd/yyyy and the time from 24h to 12h.
I tried to uninstall and reinstall it but I always get the crash.
How can I reset or change the WinNUT's date and time format?

Thanks

Alessandro

@HotelAlpha4 and @alebambi81 , could you please try the latest pre-release 8614 and provide a full crash report?

Hello,
thanks for the update.
Unfortunately it still crashes, here's the log

@alebambi81 Thank you for getting back to me so quickly. I believe I've fixed the issue, and I have a debug build building right now. Would you please download the debug build once it's finished, and upload a log here even if there's no problem?

Edit: It just finished - you can find the debug artifact at the bottom of the page. Go ahead and extract the archive, then run the included WinNUT exe.

Hi, it works now, thanks!
Here's the log
WinNUT-Client-2023-08-05.log

I'm not seeing the error being triggered there, which is not what I was expecting. Since it sounds like it's fixed though, I'll send out another pre-release so you should be able to update in an hour or so. Thank you for your help!
