NET framework error (Object reference not set to an instance of an object.)

[LafelFalafel]

I have an issue where doom launcher gives me this error whenever i try to launch it:

When I click quit there's another error window:

Here's that same error in full:

System.NullReferenceException: Object reference not set to an instance of an object.
   at DoomLauncher.MainForm.BuildColumnConfig()

   at System.Windows.Forms.Application.ThreadContext.RunMessageLoop(Int32 reason, ApplicationContext context)
   at DoomLauncher.Program.Main(String[] args)

I updated it to version 3.7.0 yesterday and it worked just fine until today when for seemingly no reason it gave me the .NET error. If I click continue doom launcher is empty and if i try to do anything i get the same error again.

I tried reinstalling and when that didn't work I uninstalled doom launcher again and the appdata directory and tried to reinstall again but the issue still occurred.

Is this when running the installer? Can you attach your DoomLauncher.sqlite file. What doesn't make sense about this is that the call stack is showing that the app is in the process of being closed. Once I get the file I will take a look.

[LafelFalafel]

It happens both when using the installer and extracting the archive. Here's my SQlite file: https://drive.google.com/file/d/1dZlMA7BWBw-Se2foUvphYgT291YfRSaE/view?usp=sharing

[nstlaurent]

Can you run this debug build and send me the errors? It will still give an error but it includes more information as to why Doom Launcher is crashing. https://www.dropbox.com/scl/fi/68ehtmpqg4vj6nwsxhjc6/DoomLauncher_3.7.0.0_debug.zip?rlkey=r5dh12e9099kt0fgr1xu8j9iy&dl=0

Multiple users have reported this issue. So far I haven't been able to reproduce it on multiple computers. Your help is very much appreciated.

Well this is weird

Forgot to post the first error:

See the end of this message for details on invoking 
just-in-time (JIT) debugging instead of this dialog box.

That's not right. Getting closer though. Can you try this one please? https://www.dropbox.com/scl/fi/ybdh83vzaidcuz8tw8okv/DoomLauncher_3.7.0.0_debug_2.zip?rlkey=26xtz6jy8dgon09c5fmtbk0av&dl=0

This time it gives only one error and just crashes:

[nstlaurent]

Perfect thank you. It just dawned on me what the problem likely is. Is your Windows set to a localization that where your decimal numbers are in the format of 12,23 instead of 12.23?

[nstlaurent]

This one should do it: https://www.dropbox.com/scl/fi/z0gj5nyzghwefljsuio30/DoomLauncher_3.7.0.0_debug_3.zip?rlkey=bf0kpsrbgqavkgorghj1ls5qd&dl=0

[LafelFalafel]

That was the issue, the build you sent works just fine. Thank you very much.

[nstlaurent]

Just pushed the official release for this fix. Thank you very much for the help. Was driving me crazy since I couldn't reproduce it on my computers.
