Console output while executing the program

Since test version and paid version are the same (the only restriction I know
of is: you can't send the tax declarations to the tax authority with the test
version), you can reproduce this issue with the test version available at
https://download.steuertipps.de/software/SSE26Standard/testversion

The report is about version 26.29.77 but prior versions showed this crash as
well.

Steps to reproduce (after default installation; WARNING: you need to set your
profile to *Windows 10*, prior versions are no longer supported by the
program):
1. Launch SSE.exe from the main install directory
2. Select the option "Steuererklärung 2020" (any other works too as far as I
can tell, but this is the main function for most people)
3. Observe the main window starting to appear and then two instances of the
crash reporter of the tax program getting launched, showing you the information
the program wants to send to the vendor (Akademische Arbeitsgemeinschaft).

I don't see anything of the crash logged to the console, the only error I can
see there is
> 0024:err:seh:dispatch_exception Fatal EXCEPTION_WINE_CXX_EXCEPTION exception (code=e06d7363) raised

Otherwise there are mostly FIXMEs, so this could very well be a missing
function somewhere.

The program itself logs the following to a file:

The non-staging version fails earlier for me and doesn't get even this far
(previous editions, up until "SteuerSparErklärung 2020", all worked fine for
me, even on non-staging versions of Wine. But those allowed Windows 7 as the
OS).

Attached you find all the output from the console and the minidump files
produced by the program itself (upload follows this initial report).

Let me know, if you need anything else.
