Stuck in Run Program

Hi, community.

I got stuck in ‘RUN PROGRAM’ without knowing any notice.
please help me out how to figure it out. what is my problem?

The following is what it happened. it keeps ‘still running’ like forever. (COPY Command)

I tried to use DOS command manually, but it works fine.

I’m curious, what’s is the character that is used instead of the backslash in file paths? Why not backslash?

Did you try using the “File command” action? It has a command to copy multiple files. No need to use “Run program”. See this tutorial article: File operations
