RCA

1. App calls [[PushNotificationsManager shared] unregisterDeviceToken];
2. App synchronously deletes the account WPAccount and it calls [_wordPressComRestApi invalidateAndCancelTasks]; in prepareForDeletion
3. (next run of the run loop) WordPressKit reaches the closure of Task { @MainActor in func POST. It tries to create a task on an invalidated session

@objc @discardableResult open func POST(_ URLString: String,
           parameters: [String: AnyObject]?,
           success: @escaping SuccessResponseBlock,
           failure: @escaping FailureReponseBlock) -> Progress? {
    Task { @MainActor in
        // URLSessionTask is created here, asynchronously
