Using Ekos Debugger is the best way to submit crash reports. But I'm not entirely sure about the "Timers cannot be stopped from another thread" issue. I've seen it before, but I was never able to track it properly.
I would do a clean install if you can. Its not worth fussing with it, and I am not honestly sure what I did to set it off the first time. If you need any assistance feel free to message me, this thread is kinda old. Thanks
Edit: I just saw that Jasem has replied! Nevermind me, however if you still want help feel free to message me still.
