### App Id

d3fwj1dkns35sh

### AWS Region

us-west-2

### Amplify Hosting feature

Access control

### Describe the bug

After enabling access restriction for auto-detected branches it can not be disabled.

### Expected behavior

I expect to be able to disable access restriction (which I enabled myself) for auto-detected branches.
Or I would expect if anything is going wrong I get the proper error message when I save the settings.

### Reproduction steps

1. Go to App settings > Edit
2. Enable branch auto-detection
3. Enable "Restrict access to autodetected branches with a username and password."
4. Click Save
5. Go to App settings > Edit
6. Disable "Restrict access to autodetected branches with a username and password."
7. Click Save
8. Refresh the Page and go to App settings > Edit
9. The "Restrict access to autodetected branches with a username and password." is still enabled.

### Build Settings

### Additional information

_No response_

Start by reproducing the issue in Amplify Hosting for app d3fwj1dkns35sh in us-west-2, following the App settings > Edit steps in the report. Check the saved access-control state after disabling restriction for auto-detected branches. Done means the setting remains disabled after saving and refreshing, or a proper error is shown.
