as saracraw already pointed out, this may have several reasons. (Thanks @saracraw)
Since you are referring to the group feature, I guess you are using a Business License or even a Company package.
The analysis of the issue itself might be needing confidential debug information that should not be shared in a public place.
Thus, I'd kindly request you to contact our support team directly at firstname.lastname@example.org.
Thanks for your understanding.
