Befort this update , the game has working correctly.
I already try to " repair " the game whit the GOG launcher

Someone had a solution ?

Had the same problem this morning when Galaxy updated and dled the new DLC for W3.

1st i pressed the "MORE" button and clicked on the "Configure" option.
On the bottum, under the "DLCS INSTALLED" i marked the square for Hearts of Stone.

2nd Although i had already dled the DLC pack(ver 2.0.0.40) like 3-4 days ago i did it again,
from the "Get backup & extras" tab.
This time the dled exe of the pack was ver 2.0.0.41 !!!!
I run the setup and W3 worked just fine.

Did not uninstall anything, just did those two steps and it worked for me.
Hope it will to the job for you also.
