Error in Xcode console when Capturing

Description

When Capturing on iPhone, the following error appears after the photo is taken, no matter the photo is successfully saved later or not.

2020-12-12 08:23:42.891912+0800 App[621:124612] [assertion] Error acquiring assertion: <NSError: 0x2829f6d00; domain: RBSAssertionErrorDomain; code: 2; reason: "Client is missing required entitlement"> {
    userInfo = {
        RBSAssertionAttribute = <RBSLegacyAttribute: 0x10476be00; requestedReason: FinishTaskUnbounded; reason: FinishTaskUnbounded; flags: PreventTaskSuspend>;
    }
}
2020-12-12 08:23:42.891986+0800 App[621:124612] [ProcessSuspension]  0x10cbd7520 - ProcessAssertion() PID 621 Unable to acquire assertion for process with PID 624

The error might only happens after certain Xcode or iOS (WKWebview) updates, but it is not confirmed yet.

It might be related to background task too.

Steps to Reproduce

1. Run the App with Xcode on real device (Xcode 12.2, iPhone, iOS13.6)
2. Take a Capture
3. See the debug console

Expected Behavior

• Expected: Should be no such error.
• Actual: The error always happens and repeats several times when taking a photo.

Logs

As above mentioned.

Environment

• Xcode: v12.2
• Capture: v0.11.4
• iPhone device name: iPhone 7 Plus
• iPhone OS: iOS 13.6

Reproduce the capture flow using Xcode 12.2 on an iPhone running iOS 13.6 and inspect the capture and possible background-task handling mentioned in the report. Confirm whether the WKWebView or platform update is involved, then verify that taking a photo no longer produces the reported assertion error in the console.
