EndNote 2025 is crashing when save new reference/closing the new reference window

I have discovered that my EndNote 2025 is crashing/closing every time when I use the add a new reference function and save new reference (after a few seconds) or closing the independent, new reference window.

The reference is saved and is available when I restart EndNote.

Anyone else having this issue? Is this a EN 2025 bug?

Best wishes
