FilePicker.pickFiles always canceled on Android (launchMode="singleInstance")

[mrsamse]

I have an Ionic project with capacitor. Now I'm trying out this code:

const result = await FilePicker.pickFiles({
  types: ["image/png", "image/jpeg", "application/pdf"],
  multiple: false,
  readData: false,
});

The UI for selecting the file opens without any problems. But when I select the file, nothing happens.
I always get this error message in the Google developer tools, when I try to debug it:

The file picker works perfectly fine on iOS and in the web. Just the android implementation has this behaviour.

This are the permissions I have set in the app. Maybe I'm missing something?

The permissions are also set correctly when I look at the app info. The app should be able to access the files.

It seems to be a misconfiguration in my app because it works with the Minimal, Reproducible Example. Does anyone have a hint for me, what the problem could be?

Okay I found the problem: The launch mode on my activity was set to "singleInstance" and with that, it doesn't work. When I set the launch mode to "singleTask" it works like intended. Same thing happens in the Minimal, Reproducible Example. Should we open an issue for that, or is that behaviour intended?
