System.IndexOutOfRangeException in Aspose.OCR.dll

While doing OCR I’m getting sometimes the following uncatched exception. As it is totally uncatched I can 't catch it and it will break my application.

I will try to figure out the corresponding image and upload it later.

Here is a Screenshot of the Stacktrace:

2022-10-19 09_52_00-anzen (Debugging) - Microsoft Visual Studio.png (90.3 KB)

Version is Aspose.OCR for .NET 22.9.0.

I could find the causing image and can reproduce the exception with it.
The file ist here: DebugOCR.png (20.7 KB)

The original image is embedded within an PDF. I’m extracting all images from this and try to OCR them.
