Mixxx has been crashing randomly when running AutoDJ for extended periods. Sometimes after 6-10 hours, sometimes after as many as 3 days, but always with the same error in Event Viewer. This time, it just froze when trying to select "Devices" from the main screen.

OS: Windows 10 Pro
CPU: Intel(R) Core(TM) i5-6400 CPU @ 2.70GHz
Video: Intel HD Graphics 530
Sound: Realtek HD Audio

The system normally crashes randomly. However, this time AutoDJ was running inside the debugger for about 7 hours. When I attempted to load a different playlist, when I tried to navigate to COMPUTER -> DEVICES, Mixxx froze.

Is this still an issue? Unfortunately your Backtrace does not contain debugging information. Did you install the pdb files?
Please comment at GitHub

I have reworked how the library tree is build up. Maybe #11230 fixes this issue?

We got responds on Launchpad:

No, this issue has been resolved. As an aside, the instructions for generating a backtrace were a bit confusing, probably because there had been an update to the process when I attempted. In any event, Mixxx has been running on a new machine with no problem. It ran for a bit more than 6 weeks 24/7 with no issues. Thanks for the follow-up!

So this can be closed.
