Object reference exception when opening file

[AdamShakhabov]

On the Spire v4.7.0 I'm encountering Object reference exception when opening a certain file.

Please see attached file for the solution and power point file. The presentation file is located at SpireObjectReferenceException\Resources\UTestParsing01.pptx.
