Natron can no longer write

I have been using Natron on an M3 Mac with no issue until now, I am trying to render out this animation but keep getting a Write error.

Write1 error: Unable to initialize output: Invalid argument

I made sure to name the file properly, I am not sure why it all of a sudden doesn’t work as I have been using Natron all morning.

Hi,

Could you take a screenshot of the writer node properties?

Hello! Have you tried using a different name for the output? Also, try deleting the write node, and creating a new one. Another way to troubleshoot is try saving in a different location (ie ssd, hdd, desktop, documents folder, etc) and see if the problem persists.
