Unable to use Run from here

Earlier i used to use “Run from here” option it was working well
The version which i used is 6.2.0
Suddenly it stopped working,. I checked . new updated was there. So i updated to 6.2.1
Eventhough , i couldnt use “Run from here”

Make sure you have a Katalon-generated browser instance already open before trying to use the option.

Ya I’m sure. Already katalon generated browser instance was open.
I’m running a whole 20 lines script. Uppose if I get issue in between. I’m correcting it and using ‘Run from here’ to continue back.
But it’s not working
