UiPath Vision has stopped working


I have to read several pages of a scanned document in PDF format and search for a specific keyword. I use the “Read PDF with OCR” activity with the Tesseract engine. After some successful runs, UiPath crashes with the error message “UiPath Vision has stopped working”. But when I restart it, it works again.

A try block does not catch this error.

All packages are up to date

Steps to reproduce:-

Current Behavior: -

Expected Behavior: Reading multiple PDF without crashing

Studio/Robot/Orchestrator Version:

Studio 2018.3.2 - 10/30/2018
Enterprise Edition

OS Version: On Microsoft Windows Server 2012 R2 Standard 64-bit
.NET Framework Version 4.7.2 or later

Thanks in advance :slight_smile:
