"For each" loop crashes after attempting first repetition


I’m having and issue regarding the “for each loop”. What I’m trying to do is to gather several excel files into a single one, My loop starts by using Win+r command and then opening each file one by one. The nested action itself works perfectly, however, once the loop begins (starting from Win+r) it stops working,

Hope you guys can lend a hand, I’ll appreciate it a lot.
