Hi,
I am facing a very weird issue where I am unable to download our own application from TestFlight for testing.
This issue only happens for one of our applications; we are able to download our other applications without any issues.
Furthermore, this only happens on one of our MacBooks; the game downloads fine on our other MacBook (macOS 15) and can run our application.
When running the console, I noticed this error being thrown when the TestFlight fails the download:
I have tried reinstalling TestFlight, clearing all instances of our application as what Finder can find, restarting the MacBook but nothing worked.
Is there anyone that faced this similar issue, or any Apple staff that could help with this?
OS version: macOS Tahoe (26 Beta) latest
TestFlight was able to download on this version previously, until one day it couldn't (and not sure why), tried downloading latest version but did not solve the issue.
Note: We noticed that we are unable to install our own application from the Appstore as well, on this MacBook that has the TestFlight issue.
