Djrx2 rekordbox link crashing windows blue screen

It sounds to me like you might have another networking service conflicting - please verify that you don't have any other system / file sharing services or server applications running in the background. If you have a VPN, you may need to disable that as well. Check that any 3rd party malware or antivirus software is disabled.

Finally, verify the configuration of the virtual networking device to ensure it's set as a private network connection, not a public one.

I also have XDJ-RX2 and get a bluescreen when attempting to load a track from the link to Rekordbox (v5 or v6).

Windows v10. Lenovo Thinkpad. MP3 music files. Drivers totally up-to-date, including chipset firmware, and I've got the latest versions of v5 and v6 installed. I always run no firewall, no VPN, no funny stuff. There's no networking involved in my DJ setup, just USB.

The link used to work at some point, then stopped working. The bluescreen is reliable 100% every time. The details of the bluescreen actually seem to change from time to time, giving different error codes. However, the most common one is:

kmode_exception_not_handled

wdf01000.sys 

I too am stuck using a flash drive and can no longer "play around" freely mixing from my music collection, which absolutely sucks.

Because my setup reproduces the bug reliably, I can offer to help you debug this problem. Otherwise, I will reformat my PC and reinstall Rekordbox in order to try to fix it.

You say the drivers are up-to-date, but is the BIOS also updated?

I have the same problem on windows 11, I have the same problem and all drivers of my computer are up to date.I have this problem whenever I sync with pioneer XDJ-RR
