Exception:

System.NullReferenceException HResult=0x80004003 Message=Object reference not set to an instance of an object. Source=Plugin.Maui.OCR StackTrace: at Plugin.Maui.OCR.OcrPatternMatcher.ExtractPattern(String input, OcrPatternConfig config) at Plugin.Maui.OCR.OcrImplementation.ProcessOcrResult(OcrResult ocrResult, OcrOptions options) at Plugin.Maui.OCR.OcrImplementation.d8.MoveNext() at Plugin.Maui.OCR.OcrImplementation.d7.MoveNext()

Works fine: return await OcrPlugin.Default.RecognizeTextAsync(imageAsBytes, options);
