That error you are seeing is most likely unrelated userscript execution errors. The error you see, likely happens when one of the popup init function has an unresolved promise, which often means something went amiss on the swift/os side. The error that is caught is logged to the console.

cryptic error message

There's not much room in the popup to add full details of the error log and probably not useful to most users. That's why the error is usually fully logged in the console.

In my experience hitting the retry link often resolves it, but obviously not always the case.

As far as error logging improvements go, which is likely unrelated to your issue:

The error message should report the exact javascript compiler error, including row and column.

Most errors are printed to the console as mentioned above. In order to access the console you'll need to plug your phone into your computer. The console will have the details of the error, for most errors, however in this case those details will probably not be useful.

The javascript instance should be isolated and not breaking the entire extension

Userscripts are isolated from each other and the failure of one script doesn't necessarily mean that all userscripts will fail to execute. That depends on how the user decides to inject their userscripts.

Again, this error you are seeing is different than a simple userscript failing to execute.

If a script crashes after the injection, the script that caused the error must be deactivated automatically, with a red icon (like this: 🚫) added as prefix of the script name in the list. Only when it compiles with no errors the script should be reactivated.

This is a big ask and feature to implement. I don't have plans for anything like this, but if you'd be willing to contribute, let me know.

Crashes are often linked only to specific websites. But userscripts deactivation is currently global. It should be deactivated only for the current website or domain. The extension should remember the user settings for a website/domain and activate or deactivate the scripts according to the user input.
