I think I have the source of the problem or one of them anyways. At least in my case. Not totally convinced but as of now it is quite likely that turning off "Allow Sensors permission to apps by default" is what caused these crashes. I did get one crash after re-enabling this setting but it was the first attempt to load the secondary profile immediately after turning this back on, which is why I'm hesitant to say I'm certain. But it hasn't reoccurred since and I've reloaded the profile 6 or 7 times without issue. Additionally, I've change numerous settings including the navigation mode from gesture to 3-button. I have also pushing orbot and organic maps over from primary and have orbot running. So I have pretty much duplicated the original setup I was having the problem with and it seems to be working as it should. Anyway, I will continue to test and with any luck be able to confirm in a day or two.
