master version of #6971

• I signed CLA
• I made sure the code in the PR follows the coding rules
• I made sure the code compiles on my machine
• I made sure there are no unnecessary changes in the code
• I made sure the title of the PR reflects the core meaning of the issue you are solving
• I made sure the commit message(s) contain a description and answer the question "Why do those changes fix that particular issue?" or "Why are those changes really necessary as improvements?"
• I made sure the commit message title starts with "fix #424242:" if there is a related issue
• I created the test (mtest, vtest, script test) to verify the changes I made

Can we see a closer review of the failing mtest reason within the github actions?
Same mtest for mu3 were happy though..

@jeetee please add error code output with description to the console. will be useful in the future
/mtest/testutils.cpp:140

I'll look into that, but mtest is currently missing as part of the project on MinGW/QtCreator by default for me; haven't looked into that yet.

So likely something changed here between build systems and or mu3 vs mu4 as well; as in mu3 this output at least was generated at one point. Or perhaps the mtests used to run under debug and now don't?

Looking for rebase and then I'll merge it
