I have seen this thread: Mixxx 2.3.0 (Stable build) crash on Windows x64 10 21H1 which refers to a similar problem in Windows x64.
Nevertheless, my problem is different not only about the operating system, but the way the failure is happening and I have my system always set to a 48000 Hz sample rate.
When I run AutoDJ mode, the playback is stopped after an hour or so.
Please let me know what do I need to post in order to diagnose.
Thanks in advance.
