QGC White Screen only

When first using my HereLink after updating to the latest firmware QGC was working fine, However I was diving into the video settings and accidentally changed the output to UDP. Now QGC will not open and only gives a blank white screen. Any help would be appreciated.

Thanks in advance

Have you tried rebooting the Herelink or QGC app?
Also try to reset the QGC in settings
If it still doesn’t work, try to reset your Herelink to factory
