Random distortion using software link Windows 11 new Alienware laptop and 7.2.10

Been using all my tracks perfectly for a whole year (and 5 years previous with Traktor) with an old windows 10 laptop. Now a new windows 11 laptop alienware 16 x Aurora and RX3 its been happening since i acquired the Alienware 3 weeks ago. RX3 controller fully up to date. It's different tracks, different durations of operation, (starts from 1.5 hours, then down to 10 minutes after using all day) its totally random but only happens when software linked. Rekordbox 7.2.10.0333 . Playing on usbs are totally fine, even same tracks, its is NOT a track issue. Issue arises randomly during live radio broadcast (using behringer AC222) so move to play on usbs and restart rekordbox (or simply unlupg the controller or turn off and on again) and restart again with software link, all is good again for a period. same tracks, no distortion. continues without issues or distortion, for a random period of time, then the distortion reappears again (could be anything from 2 minutes to 4 hours or longer). sets are recorded with knowledge of time stamps so easy to hear distortion points if of interest. In one recorded example, the distortion appeared, moved to usbs about to mix in and the distortion disappeared on the software linked track. Checked all cables, moved them all around, tried others simply no change-its not a cabling issue.

256 buffer size changed yesterday to 512, problem still appears, 44.1hz.. Using ChatGPT for various fixes in Rekordbox and Windows 11, all to no avial.
Install the latest RX3 ASIO driver-done (same file as 3 weeks ago)
Rekordbox using RX3 ASIO + internal mixing
All these not even in the machine to disable:
