After the update to a Photoshop 24.2, many files can't exports artboards. (from 4 to 30 artboards - is not matters).
I did some tests in almost 8 PCs (Win11) with update. (with the same troubles).
The export procedure (Ctrl+Alt+Shift+W) is lazy with to much delay and the end we receive a POPUP without data.
Now we came BACK to the 24.11.
*by the way, I'm a BETA TESTER and i dont have issues in a 24.3 version.
