Downloaded the newest Traktor Pro 4.3 last week. I'm on a 14inch MacBook Pro M1 Max 32GB on MacOS Sequoia 15.7.1 (highest supported MacOS as Tahoe is not yet supported by Traktor), and last night, the equipment provided by the venue was DJM 900NXS2 and 1x CDJ 2000 NSX (Deck A) and 1x CDJ 2000NSX 2 (Deck B).
15 minutes into the set, I noticed that I could not load a track onto Deck A, and then 30 seconds later, music completely cut out. Very thankfully I had a rekordbox USB as backup and played off that while I diagnosed the problem. Interestingly, Traktor Pro was completely frozen, and I could not exit or drag another track, which is a rare from my experience even during a crash. I had to power off my computer by holding the power button, and booted up Traktor Pro version 4.1.0 146, which for me, has been the most stable version with my configuration. After doing so, I had no issues for the rest of the set. I've shared on this forum that Traktor Pro 4.2 has also crashed on me during live sets but not as severe as this latest version of Traktor Pro 4.3, and I hope this data point helps fellow Traktor DJs who are using a similar config as I am: the latest Apple Silicon, the highest supported MacOS, and club standard Pioneer DJM/CDJ combinations regularly for live sets.
I would also like to add that he lack of quality control from NI to ensure that the newest versions of Traktor Pro are stable is disheartening. However, I still play my best on Traktor Pro as opposed to rekordbox or Serato, and I hope the best for NI and Traktor Pro; there's no DJ software like it. Proud to be one of 3 DJs in my talent agency out of 70+ that still use it.
