Hello!
I've been trying to get assessment mode working on my application. So far so good, seems to work on almost all of the laptops, except one. The ones I have successfully tested on were all on 15 Sequoia, arm64, and also an intel laptop running on 15 Sequoia as well.
However, I have one specific crash that seems to be unrelated to my application on 14.5 Sonoma, 2019 intel. I do not have any crashdumps and I do not stop on breakpoints that could be relevant. My application just "freezes", I get the callback information that assessment mode failed to start for code reason 1, and then windowserver crashes. I do not see any crashdumps related to my application. Maybe some of you have a specific idea what am I doing wrong? It's a bit interesting that It only happens on this device.
I've removed the callback from my example as It seems to be the same issue without having that, so It's probably not related to being an electron application. Entitlements are properly set, provision profile properly used.
