When compiled as an exe TesseractEngine won't initialize

[AlexBaldwin42]

This is a .NET 6 console app. With Tesseract and Tesseract.Drawing Version 4.1.1
It will work when debugging and dotnet run
It will not work with -p:PublishSingleFile=true set but will run without it.
It will not work when I publish it as an exe using this.
dotnet publish --output "C:\" --runtime win-x64 --configuration Release -p:PublishSingleFile=true -p:PublishTrimmed=true --self-contained true
It fails on
var engine = new TesseractEngine(@"./tessdata", "eng", EngineMode.Default))
The training data is in that folder it is the same folder the executable is being run.
I have tried using Directory.GetCurrentDirectory() as the path.
I have tried having the training data in the same folder as the executable with @"." path.
All these methods work when debugging but not when published as a single file executable.

I am having the same problem using .NET 6 and Windows Forms. Debugging works just fine but when publishing, it wont run. Did you manage to make it work?

This is my Error

I got it to run by using
var engine = new TesseractEngine(@"//", "eng", EngineMode.Default))
while having the "tessdata" folder in the published directory.
