I have the same issue, on ipad OS 18.3(22D5034e).
My iphone (18.2) is normal.
The issue observed is as follows: The settings page of the extension keeps reloading repeatedly, appearing as constant flickering. After flickering for a long time, the console page eventually appears, but it is impossible to import any configuration files or scripts. Any attempt to perform an action results in infinite flickering.

I have same issue, every extension control panel can’t open. “Immersive transition” recently updated and I can enter its settings page.

I'm updating my iPad to 18.3 currently to reproduce the issue.

This is a funny iOS 18.3 Safari bug. Setting document.title or starting communication with the background page earlier than ~200ms after page load makes the page force reload. 🤷

I'll add a workaround to the next release.
