Does it recover if you restart node-red and refresh the browser page?
I tried restarting my computer also but it's not worked
Please stop node red and restart it in a terminal window. Post the full output that you see.
I closed the terminal
I don't understand why you have posted that message.
I created 1 slider how it showing 2 sliders
I meant you to restart node-red in a terminal and post the terminal output here. The output that says "Welcome to node-red".
Man!!! everything deleted
That is because the command
node-red restart
starts node red using a flows file called restart which does not exist. Look at the log you posted to see. If you stop node red and start it again normally then you will be back with the default flows file. Please do that and post the log you get with that flows file. Please copy/paste rather than screenshot.

again it showing dashboard widget double
Try with a new flows file, so run
node-red testflows
which will give you a new empty flows file called testflows. Then Add a widget, deploy, and check the dashboard.
If I create new widgets means it showing only one
If you create new widgets in your real flow does it show two?
