I have read some other posts regarding the same problem where a moderator has provided a link on how to create a "debug log". At some point, in the step-by-step procedure, one has to reproduce the problem causing the pop-up with the aforementioned message above to appear. The problem is that I cannot reproduce the problem, for it can appear suddenly out of the blue, even when I am not doing anything at all on the computer.
I have to acknowledge, however, that I haven't seen the pop-up for a while since I started that post 5 days ago. Here is hoping it stayed that way..
