Seeing the same here—got to 1.86GB, the animation stalled / stuttered, and then crashed out of memory. The progress bar was full as far as I can tell, so perhaps it's at the end of discovery whilst populating the list?
More than happy to test / debug.
Edit: This was on 2nd and subsequent runs. First run did complete OK. Will try on fresh boot.
Edit 2: Clean boot, nothing running but task manager, and it completed at 1.85GB no error.
Edit 3: Accidentally quit the app again (see my other feature request 🙂 ), and 2nd run also terminates with out of memory. Perhaps you might have more luck reproducing on the second run?
