iPad应用崩溃求助：Expected a popover view, found (null)

我遇到一起iPad应用崩溃问题，崩溃堆栈信息如下：

目前无法通过堆栈信息明确崩溃原因，我认为相关的代码如下，但未发现明显问题：

+ (void)openFileShareExtensionWithURL:(NSURL *)url
                 navigationController:(UIViewController *)vc {
    FileOpenHelper *helper = [[FileOpenHelper alloc] init];
    docInteractionController = [UIDocumentInteractionController interactionControllerWithURL:url];
    docInteractionController.delegate = helper;
    CGRect frame;
    if ([UIDevice currentDevice].isiPad) {
        frame = CGRectMake(CGRectGetWidth(vc.view.frame) / 2.0, [BHStyles topNavInsetHeight] + 10, 0, 0);
    } else {
        frame = vc.view.bounds;
    }
    BOOL r = [docInteractionController presentOptionsMenuFromRect:frame
                                                           inView:vc.view
                                                         animated:YES];
    
    if (!r) {
        [SVProgressHUD showErrorWithStatus:NSLocalizedString(@"Storage_NoSupport", nil) duration:1.5f];
    }
}

我尝试复现该崩溃，但未能成功，请求协助排查崩溃原因。
