The program crashes at launch; SQLite Error 1

[AdamEternal]

• Platform: Windows 11 25H2
• Paradox Launcher: 2026.8.1
• Stellaris: 4.4.6
• Tech Relations: v1.5.6

I followed the instructions. I:

1. Installed the .NET desktop runtime for Windows.
2. Downloaded the Windows version of StlTechRelGen.
3. Extracted the tool.
4. Created the target mod.
5. Put the target mod on the bottom of the load order.
6. Launched Stellaris (for good measure).
7. Closed the game and all launchers.
8. Ran the executable, both by double-clicking and via terminal (both PowerShell and the old CMD line).

Below is the error I receive, with my file path replaced with [Path].

PS [Path]> .\StlTechRelGen.exe
