App freezes or fails to launch after enabling JIT (iPad Air 8, iPadOS 26.3)

[Lhy-wed]

Description

Dear Developer,
I am experiencing an issue where an app requiring JIT cannot launch properly within LiveContainer. The app installs and opens normally without JIT. However, when I configure it to "Launch with JIT" (using stikdebug 3.0.1), the following happens:

1. I click to launch the app.
2. It automatically jumps to stikdebug.
3. An error message appears (please see the attached screenshot and execution logs).
4. JIT acquisition fails.
   Troubleshooting steps I have already taken:
   • LocalDevVPN: Always remained active throughout the process.
   • DDI: I clicked "Redownload DDI" in the settings, which completed successfully (green text appeared), but retrying JIT acquisition still results in the same error.
   • Alternative Version: When using stikdebug 2.7.3, the device completely freezes/hangs upon jumping back to LiveContainer.
   • Sideloading: I tried testing with a separately signed IPA, but the error persists.
   • Pairing File: I have re-exported and imported the pairing file multiple times.
   • System Settings: Developer Mode is confirmed to be ON.

Steps to Reproduce

Refer to the above

Expected Behavior

Successfully obtain jit permission and successfully run the app that requires jit permission

Hi, I got the same issue. Seems like it does not work for iPad Air 8 only.

I think iPad Air 8 is missing from the DDI

希望不是新ipad的硬件限制
I hope it's not the hardware limitation of the new iPad.

Supplement: "Developer Disk Image (iOS 17+): Failed: BadBuildManifest" will be prompted when obtaining the fairing file in the device pair.

补充：在idevice pair获取fairing file时会提示“Developer Disk Image (iOS 17+): Failed: BadBuildManifest“

Just need to wait for the repo that has the DDI to be updated/

Thanks for letting me know! Do you have a rough estimate of how long it might take for the DDI repo to be updated?

Also, once it's updated, will I need to download a new version of StikDebug, or should I just use the 'Redownload DDI' option in the settings? Thanks again for your help!

I've heard some talk about Apple blocking JIT at a hardware level on newer models like the iPad Air 8. Do you know if this is actually the case?

Delete the existing ddi files so StikDebug downloads the new ones

I have delete the entire Stikdebug app, and clicked the Redownload DDI, still facing the below issue:
