Dear All,

 

I am experencing the following problem on FME (FME Desktop 2022.1.0.0 - Build 22618 - WIN64)  : when I work with PythonCaller, my workspaces randomly crash.

For example, starting from empty workspace, I add a Creator followed by a PythonCaller ; run to the PythonCaller -> it works fine ; I add "import arcpy" in the PythonCaller and run -> it works ; I add "print("hello")" in any function of the FeatureProcessor class -> it crashes.

Also, the crashes happen in an unpredictable way : sometimes, it crashes after having inserted "import arcpy" ; sometimes I can add 2-3 five more lines in the function of the FeatureProcessor and it works and then after 1 more line it crashes.

By crashing, I mean the following : after clicking "run", the mouse cursor takes the form of a blue waiting circle during a few seconds and the window suddenly closes -> when it crashes, it seems that the translation never really starts (nothing happens in the "translation log" window), there is no log file produced.

I have been trying thousands of things to solve this problem for more than a week now (changing Python interpreter, working on another machine, etc., etc.), I am running out of ideas...

 

Has any of you already encountered such a problem ?

 

Thanks

update : by looking at the Window event observer, I see that the ''module défaillant" failure module ?] was often Qt6_Widgets_fme.dll (more rarely Qt6Core_fme.dll) => do you know what is the purpose of the Qt6_Widgets_fme.dll ?image.png

It is a known issue. Please check this article for more information. An update of the FME Version will resolve the error.
