twinmotion 2023.2.4 don't make videos

good morning,
I have a new ouissant laptop on which I have just installed TM. It will render images, but not videos.
After choosing a video, it generates an mp4 file that VLC can’t play.
In fact, when it comes to exporting the file, it doesn’t work normally: it pretends to calculate the rendering, the little window closes in two seconds, and produces an unreadable file.
This is version 2023.2.4
thanks for your help

deleted Twini motion, the epic games launcher and rewrapped them, and it’s the same.
