The program opens a ImageMagick windows instead of trimming the video

[JoaoP12]

I tried to run the code the first time, then it asked me to select ImageMagick .exe file, after doing that, a ImageMagick window opened. I thought the window would open and then close to go on with the execution, but it didn't work, and when I close the window manually, the program throws the error in the video attached. Obs: I was using Windows 10. Python's version = 3.8.3 ImageMagick-7.0.10-Q16-HDRI All requirements were installed from requirements.txt.
