"System Extension Blocked" pop-up cann't be click on macOS 12.4

I developed a screen watermarking program that worked fine before macOS 12.4. After upgrading to 12.4, "System Extension Blocked" pop-up cann't be click, but the other window is ok. Any body can tell me the macOS 12.4 has do what to "System Extension Blocked" pop-up !!! my sample code like this

code-block
NSScreen *screen = [NSScreen screens][0];

CGFloat windowWidth = screen.frame.size.width;
CGFloat windowHeight = screen.frame.size.height;
CGFloat x = screen.frame.origin.x;
CGFloat y = screen.frame.origin.y;

MyView* view = [[MyView alloc]initWithFrame:NSMakeRect(0, 0, windowWidth, windowHeight)];

NSWindow* window = [[NSPanel alloc] initWithContentRect:NSMakeRect(0, 0, windowWidth, windowHeight)
                                              styleMask: NSWindowStyleMaskBorderless | NSWindowStyleMaskNonactivatingPanel
                                                backing:NSBackingStoreBuffered
                                                  defer:NO];
[window setOpaque:NO];
[window setBackgroundColor:[NSColor clearColor]];
[window setCollectionBehavior:NSWindowCollectionBehaviorCanJoinAllSpaces | NSWindowCollectionBehaviorFullScreenAuxiliary];
[window setIgnoresMouseEvents:YES];
[window setHasShadow:NO];
[window setLevel:NSScreenSaverWindowLevel];
[window setContentView:views];

[window makeKeyAndOrderFront:nil];

and draw in MyView

code-block
- (void)drawRect:(NSRect)dirtyRect
{
    NSRect screen = [self bounds];

    int SW = screen.size.width;
    int SH = screen.size.height;

    [[NSColor clearColor] set];

    NSRectFill(screen);

    NSString * strH= @"watermark test.";

    NSMutableDictionary *md = [NSMutableDictionary dictionary];
    [md setObject:[NSFont fontWithName:@"Times" size:80] forKey:NSFontAttributeName];

    [strH drawAtPoint:NSMakePoint(SH*0.5, SH*0.5) withAttributes:md];

    [self setNeedsDisplay:YES];
}
