Notarization accepted, but the staple and validate action failed! Error 65.

Hi guys,

I am new to publishing apps on Apple Store. I used python, pyside6, torch, pyinstaller to build an app for Apple Store. For codesigning, I used the correct "Developer ID Application" to sign the code. When I validate the .app file (codesign -vv --strict ), I got the following

my_app.app: valid on disk
my_app.app: satisfies its Designated Requirement

Next, I used ditto to "ditto -c -k --sequesterRsrc --keepParent my_app.app my_app.zip" to zip it. Then, I submitted this my_app.zip file for notarization with "xcrun notarytool submit ..." and got the following "accepted" message.

Received new status: Accepted
Current status: Accepted...............
[20:08:54.530Z] Info [API] Submission in terminal status: Accepted
Processing complete

After that, I want to staple it with "xcrun stapler staple my_app.app", but I got the following

Could not validate ticket for my_app.app
The staple and validate action failed! Error 65.

To further investigate it, I ran "spctl -a -vvv my_app.app" and got

my_app.app: rejected
source=Unnotarized Developer ID
origin=Developer ID Application...

I don't know why this would happen after notarization accepted. Could someone help me understand this issue? Thanks!
