VLC media player error while dragging files

Hello,
I try to open a movie in VLC, which worked fine until today. When I tried to open the movie this window blocked my VLC, I tried to open it again, restarted the laptop and still this problem. I don’t know the VLC program very well, so I don’t know what to do. How can I fix this problem and how can I prevent this ?
Regards !
