DEXI drone camera is not working + controls of the right side of the radiomaster controller isnt working

We are part of a robotics team that is competing soon with a DEXI drone that is facing some issues. We have done the the things to set it up like in the video tutorial by Dennis Baldwin and we even reached out to him and resolved another issue relating to it (we accidentally downloaded the file for a different drone instead of the DEXI and he helped us download the DEXI one) and once we went into the website to see what the camera is detecting, it was in the loading screen and would not load anything no matter how long we waited. The second issue was with the radiomaster controller having the controls reversed. We had this issue previously and after changing the External crossfire mode from CRSF to OFF, it was resolved, but when facing another issue, we changed it back to CRSF and now when we turned it back to OFF the controls are still reversed. The competition is tomorrow and we need to get these issues resolved before the end of Saturday. If anyone has any potential solutions, we need the input and ideas.

Please check your camera cable as well as the camera port you’re plugged into. More often than not this is the problem with the video feed. Regarding your controller issues can you elaborate a bit more. When you say they are reversed where are you seeing this? Are you the QGC radio setup screen? Are you going to be at the Austin or Haslet competition? We will have people there to assist with technical issues.
