Xcode – Mac menu bar app crashing on app launch as notarized app only: failed to get text offset for /Applications/… (#3) No such process

I am developing a macos menu bar app, and for some reason, when I archive, notarize & export the app to my Applications folder and run the app, it crashes instantly. When I use the Console app, I see the following error messages:

myapp[30188]: AppSandbox request successful

Channel could not return listener port.

activating connection: mach=false listener=false peer=false name=com.apple.hiservices-xpcservice

activating connection: mach=true listener=false peer=false name=com.apple.window_proxies

invalidated because the current process cancelled the connection by calling xpc_connection_cancel()

When I run the app in Xcode (in debug mode & release mode), there are no Warning messages except this one for Sparkle (I am relatively sure it is unrelated to my issue but including here for brevity):

Warning: Background app automatically schedules for update checks but does not implement gentle reminders. As a result, users may not take notice to update alerts that show up in the background. Please visit https://sparkle-project.org/documentation/gentle-reminders for more information. This warning will only be logged once.

Here is a link to the .app file binary.

I gave my app’s binary to a friend and faced these error messages in Console app, but I have not been able to reproduce them myself.

Sandbox: myapp(9044) deny(1) file-read-data /Users/user/Downloads/myapp.app

IDENTITY_ATTRIBUTION: Failed to copy signing info for 9044, responsible for /private/var/folders/nt/40hq8tkx0tgb7c4fw5_n79wr0000gn/T/AppTranslocation/345F7E81-EE9E-4ADF-A66F-589A6647291D/d/myapp.app/Contents/MacOS/myapp: #-67065: Error Domain=NSOSStatusErrorDomain Code=-67065 "(null)"

I have tried the following to stop the app from crashing, all to no avail:

• Clean Xcode
• Delete Xcode Derived Data
• Restart Mac
• Build app with an alternative bundle identifier
• Removed Sparkle package and re-archived, notarized app
• Enable App Sandbox in Xcode Project > Target > Signing
• Added com.apple.security.automation.apple-events to app entitlements file
• Replaced the ‘Developer ID Application Certificate’ from Keychain with a newly generated certificate
• Use Xcode Manual Signing instead of automatic. (Create dev, release provisioning profiles, app id)

Additional context

• Xcode 15.2
• MacOS Sonoma 14.5
• Xcode minimum deployment: 13.0

Package Dependancies:
