Where can I find an error log?

I’m testing the 6.0 release, found some potential bugs, but before submitting a report at Issues · KiCad / KiCad Source Code / kicad · GitLab I’d like to investigate possible causes first.

However, I’m not able to locate any error log or any equivalent debug output (command line…)

The question was already asked, but got no answer: Is there an Error Log?

Google search is of no help, but I may not use the right terms…
Thank you for your help.

There’s no error log. But it’s OK to describe the bugs here, maybe someone can help and find more information for the reports.

Thanks, I just posted the problem I was referring to.
