Describe the bug After the scanning, I receive a error message saying: System.Exception: Could not initialize an instance of the type 'CoreGraphics.CGlmage': handle is null. It is possible to ignore this condition by setting ObjCRuntime.Class.ThrowOn|nitFailure to false. And no documents are shown, even though the scanning is over.

To Reproduce Steps to reproduce the behavior:

  1. Scan the document
  2. Scan will begin
  3. After end of the scan, error shows up

Expected behavior No error should show up.

Desktop (please complete the following information):

What version of NAPS2 are you using? There was a similar issue that was fixed in 7.1.2.

Hi, I updated the app and the issue is gone, I was using an older version. Thanks for your help and an amazing tool! :)
