VAMUpdater doesn't start

[lol715]

Recently, I have been having an issue with the updater. I open it, it loads for 4 seconds, then quits. The directory is at C:/vam, I have added it to firewall and antivirus exclusion lists. Event Viewer also mentions a .NET unhandled exception, which I have put below.

This is beyond my .NET comprehension, but this is what ChatGPT had to say:

This exception, System.IO.FileFormatException, suggests that there's a problem with a font file being loaded by the WPF text rendering system. The stack trace indicates that the failure occurs during font selection and glyph mapping.

Possible Causes and Solutions:​

1. Corrupt or Invalid Font File
   • A malformed or corrupted font installed on the system may be causing the exception.
   • Solution:
     • Check recently installed fonts.
     • Try removing suspicious fonts and restarting the application.
     • Run chkdsk /f on your system to ensure no disk corruption affecting font files.
2. Unsupported Font Format
   • The application may be trying to load an unsupported or badly formatted font file.
   • Solution:
     • Try switching to a different font in your application.
     • Ensure that all fonts used are valid .ttf or .otf files.
3. Font Cache Corruption
   • Windows caches fonts to improve performance, and corruption in the font cache can cause issues.
   • Solution:
     • Delete the font cache file (C:\Windows\System32\FNTCACHE.DAT).
     • Restart the computer to regenerate the cache.
4. Permissions Issues
   • If the application does not have the necessary permissions to access font files, this could lead to errors.
   • Solution:
     • Run the application as an administrator. (Personal Note from Me: I am not recommending you run the updater with Admin privileges, no offense to the VAM Devs. Do this at your own risk).
     • Ensure that the C:\Windows\Fonts folder and font files have the correct read permissions.
5. WPF Bug or .NET Framework Issue
   • If you're using an older version of .NET, it could be a bug in font handling.
   • Solution:
     • Update .NET and Windows to the latest version.
     • If running on a specific Windows build, check if there are known issues with font rendering.

The question is, what happened in between working and not working? That could show clues.
