Hi, i have many students using kinovea through a remote desktop and they are getting the following message preventing from saving any work.

Unhandled exception has occurred in your application. If you click Continue, the application will ignore this error and attempt to continue. If you Quit the application will close immediately.
Collection was modified; enumeration operation may not execute.

Hi, that definitely sounds like a bug.
Could you connect to one of the machine and go to the log folder (via help menu) and then collect the files whose name start with "Unhandled exception"? These contain the last things the program was doing before the issue and will help me identify exactly where the problem is. Send them to joan at kinovea dot org or create an issue on github and attach them there.
If possible also collect the log.txt and log.txt.1 files, send these ones via mail only as they can sometimes contain personal data like file paths.
Thank you.

What ever happened with this?  I keep getting crashes with the same message after reverting to 24.1.1

It's a very generic error message, I can't investigate without more information on how to reproduce the problem or at least a better understanding of what the program was doing when it happened.

Can you send me the Unhandled exception files and log files or create a github issue? Does it happen only on 2024.1 or also 2025.1? Are you also using remote desktop?
