I'm experiencing the same issue. The background script only loads once or twice on iOS 17.5 beta 1, 2, and 3, whereas it works as expected on iOS 17.4.1.
My app doesn't include a content script, only a background script. To resolve the issue, I have to force quit Safari and relaunch it. Additionally, I attempted to create a new Safari extension project. In the background script, I added a listener to webNavigation.onBeforeNavigate, but it only triggers once or twice and then stops working. To get it to trigger again, I need to tap the 'aA' menu and then tap the extension popup menu, but it still only functions sporadically.

Just update your project Build Version and run again.
I have exactly the same issue with Safari on macOS Monterey.
After I changed to Chrome the uploading error finally shows.
