Winforms app runs fine from bin/debug or bin/release, but not outside

I have developed a Winforms C# app (.NET Framework 4.8), which used to run fine. Last change, I decided to add a Map control using Gmap.NET. At first everything looked fine, in debug, so gave it a go, and built a release version (IMPORTANT NOTE: my solution has 2 Projects - the first contains the Winform app, and the second is a Setup Project created with the Microsoft Visual Studio Installer Projects 2022 extension).

From that starting point:

1. The Release build was succesful. Installed the new version --> crashes on start (splash screen briefly shows, and then disappears. Main form does not load)
2. I did some research, and it looks like GMap.net has some issues, and I had to manually edit the .csproj file to get all dependencies right (explained in this question)
   3.Apparently some other reference was wrong, as it was still not working. I cleaned up Nuget packages for the solution, as well as referenced dlls

Current status:

• No exception thrown. Program runs fine on debug mode
• Program runs fine if I click on the .exe in bin/debug or bin/release of the Winform project
• Program hangs on start f I copy the whole bin/debug or bin/release to other location and start from there
• Program crashes on start if I install it and launch normally

I am at a loss here. I have tried Assembly Log Binding Viewer but only some messages about XML.Serialzers there and, according to this question it is fine to ignore them. I have tried debugging without the "Just my code" option, but I do not see anything there. I have also populated my code with writes to a log file and I can see there that:

• When launched from a copy of the bin (debug or release)folder elsewhere, the program writes the log as if it was completely initialized, but the main form is hung and does not show the controls

• When launched from the bin (debug or release) folder, runs as intended

• When launched from the instalation path it crashes immediately and the log shows traces up to the call to InitializeComponent() :

public Form1()
        {
            using (StreamWriter sw = File.AppendText(Application.UserAppDataPath + @"\mainlog.txt"))
            {
                sw.WriteLine("Initializing Form 1 components");
            }

            InitializeComponent();

            using (StreamWriter sw = File.AppendText(Application.UserAppDataPath + @"\mainlog.txt"))
            {
                sw.WriteLine("Form 1 components initialized");
            }

to be precise, last message in the log file is "Initializing Form 1 components" but, if I try to debug step by step inside InitializeComponent() I see no exception, and it works (as always in DEbug mode from Visual Studio)

I am suspecting that some of my code is referencing a DLL and, when it is run outside the bin folder, it cannot find it. It should be included by the installer, though, and I am not able to find any exception (tried placing some try-catch blocks around to no avail) or message giving me a hint. So I am open to test any options... just be kind and constructive, as I am a HW guy out of his comfort zone, and some of my code might be a mess. I can paste specific code blocks per request, but the whole app is now sitting at roughly 30K lines, so we better be specific (also that is the reason I don not throw this into the bin and start all over).

EDIT1: after @Deolus comment, I looked again in the Event Viewer and I see this:

Ok, it finally works.

It all boils down to not having the right version of SQLite.Interop.dll. As my "\packages\System.Data.SQLite.Core.1.0.117.0" and "\packages\System.Data.SQLite.1.0.117.0" folders only showed a .p7s and .nupkg file, and now dlls at all, I had downloaded the dlls, and it seems they were wrong. Making a search for SQLite.Interop.dll in my ackages folder found the right ones under "\packages\Stub.System.Data.SQLite.Core.NetFramework.1.0.117.0\build\net46\x64" and "\packages\Stub.System.Data.SQLite.Core.NetFramework.1.0.117.0\build\net46\x86".

Adding those files, as explained here did the trick
