Failed to enable JIT for {app} / The Developer disk image could not be installed

Hi,

I have the following error while trying to run JIT via AltServer.

I had installed AltStore with AltServer.
At a point, JIT was working.
Then I reinstall AltStore within AltStore with the IPA to be able to get ride of the Widget in order to spare an App IDs.

I had found the Disk Image for my iOS version here
https://github.com/mspvirajpatel/Xcode_Developer_Disk_Images/releases/tag/15.7
but I do not know to put it...

I try to run JIT from AltStore, it does not work either.

Please note, that I am on the same Wi-Fi network,
that I activated the phone connection on the same Wi-Fi,
that I even tested it with a cable,
and I tested to run JIT with other Apps,
I have reinstall everything
still the same error message...

Could you please help me ?
