I ran this script in the background and it doesn't stop running and everything is slow, how do I stop it if I can't load any pages?

Fast traslate

Icon translate

var gr = new GlideRecord('sc_request');
gr.query();
while(gr.next()) {
gr.u_opened_for=gr.requested_for.getDisplayValue(); 
gr.setLimit(5);
gr.query(); gr.print();
//gr.update();
}

I hope your issue is resolved.

While looping through gr, you are doing a gr.query()

This caused the infinite loop situation.
