I have a script which continue works on Excel

Hi Team,
I have developed a script on which the Robot is working on internet Explorer continuously after Working for 1 or 1.5 hr it get stuck it seems that the internet explorer window is not getting loaded properly due to which the Robo is failing.

when I checked the Memory usage of Internet Explorer it was 984.08 Mb and Uipath Robot was taking memory 57.7 MB and uipath Studio was taking 452.mb .

Why Internet Explorer is getting stuck is there is any way to resolve it?

It is not enough to close the application (IE), you have to kill it to make sure it is not running after your workflow runs
