Failed to execute addon 'misra' - exitcode is 1

[vix]

I run cppcheck 2.19 from the GUI on Windows and I created a project file (*.cppcheck).

I enabled Addons >> Coding standards >> MISRA C 2012 ...
The file with MISRA rules starts in this way:

Appendix A Summary of guidelines

Rule 1.1 Required
Any implementation-defined behaviour on which the output of the
program depends shall be documented and understood

-------------------------------------------------------------------------------
Rule 2.1 Required
All source files shall compile without any compilation errors
Requirements traceability

When I run the analysis I get the following error:

Id: internalError
Bailing out from analysis: Checking file failed: Failed to execute addon 'misra' - exitcode is 1: python.exe "C:\Program Files\Cppcheck\addons\runaddon.py" "C:\Program Files\Cppcheck\addons\misra.py" --cli --rule-texts=D:/repos/..../misra_rules_2012.txt D:\repos\..\xxxxx-cppcheck-build-dir\main.a1.dump
Output:

Is there something wrong in my misra rule file?

should I provide any additional info on this error?
