my site https://worldunscrambler.net/ is brand new... never registered before I checked the history and can confirm that.....Google index my site but bing gives me an error..

The inspected URL is known to Bing but has some issues which are preventing indexation. We recommend you follow Bing Webmaster Guidelines to increase your chances of indexation.

I don't know why they are doing this to me... I am very frustrated and don't know how to fix that... I contact bing support many times through the search console but they are not replying to me....
if anyone has the solution please please help me out.
