I used it well in the previous version
I recently switched to Windows 11 version and tried to use it by downloading a new kinovea, but the video file won't open. It is an mp4 file, and the video is played on the computer. Error in calling, failure to open documents
The phrase comes up What's the problem
Is the file in the OneDrive folder by any chance? I'm getting more and more reports of people trying to open files that are synchronized to OneDrive and these files aren't really there even if Windows shows them as if they were local. I have to check how to handle this case gracefully but if that's your case you could temporarily copy the files to another folder and try again. This will force Windows to actually download the files.
Another known issue like this is specifically for the Korean locale when the file name has Hangul characters in it.
I think I've also had this issue when Videos are uploading from your local HD to Onedrive and you try to play them back.
