Hello, Im currently having signing issues submitting my Swift macOS app to App Store Connect. After submitting it using Xcode I receive an e-mail with these issues: ITMS-90238: Invalid Signature - The main app bundle CodeMenu at path CodeMenu.app has following signing error(s): nested code is modified or invalid .

ITMS-90296: App sandbox not enabled - The following executables must include the 'com.apple.security.app-sandbox' entitlement with a Boolean value of true in the entitlements property list: [[CodeMenu.app/Contents/MacOS/CodeMenu]] Refer to App Sandbox page at https://developer.apple.com/documentation/security/app_sandbox for more information on sandboxing your app. The app has required entitlements enabled, like App Sandbox and Hardened Runtime. I don't know what can be the cause of it, but from what I read I'm guessing that something is somewhere it isn't meant to be and the other issues are a result of it. However, I don't know how can I begin debugging this. thank you in advance.
