DDJ FLX6 stopped letting me used some buttons

I am using rekordbox on its latest update, i believe it s 6.6. and my controller was working fine last week and I plugged it in 2 days ago and suddenly most buttons won't work. I can play songs but I cannot search and load up for songs using my controller, I cannot use the loop buttons, cannot use the pad or any effects. I thought it was rekordbox at first so I reinstalled it but nothing. Tried a different computer and nothing, same outcome. I barely have had this controller for 2 months, so for this to happen is very upsetting.

I used the following computers:

-Mac with iOS El Capitan (worked fine before)

-Mac with iOS Catalina

When first connected all the lights light up, which makes me think maybe it could poor usb connection, I am getting a new usb-b cable connector today to see if it was the problem. Otherwise, any clue of what it could be?
