The target process being debugged needs the get-task-allow entitlement . you can resign the app with get-task-allow entitlement as a temporary workaround. then debugserver will work!

I believe they have fixed it already.
Next "Unc0ver Jailbreak Resources" update in Cydia App should solve it.

Thanks, I believe they have fixed it already.

I'm having the same issue, latest version of u0. My device is iPX 12.1.1 @Amoystyle

On Electra I hit the same. Without changing the get-task-allow entitlement, and going through the whole re-signing process, I was able to get it working by loading tweaks when I ran my jailbreak.

How do you make it work? You made some miraculous tweaks to avoid it ?
