Thank you it work partially, backend don't display full preview but atleast display on admin side. I have to work again for look and feel css again it's removed. no problem i;ll apply that again.
I examined the markup on the front end using the browser dev tools, and I can see that the Container block is set to take up 2/3 of the width (the other View is in a 1/3 width column), and that this width is available to the View output. But the View itself appears set to display the results in a grid, and the single result is displaying in a fraction of the available 2/3 column width.
Unfortunately, because the View cannot be edited—I mentioned that the Views were somehow corrupted—it is not possible to make any changes.
The only solution in this case is to delete that View block and insert a new View block, and create a new View to recreate the output that you want to appear there.
? junk character issue is resolve by my self please forget it. But really toolset is very very sensitive if we do any single change in page or template this junk character issue started again i notice multiple times and again we have to open all page and save it twice or multiple time by save without any change unless it go again 🙂
