Game won't launch since 4.0 update

[Romanito]

Hi,

I had version 1.32 of the game, I launched it before updating it and it worked fine.
I installed the 4.0 update through GOG Galaxy, the game won't launch since then.
witcher3.exe can be seen in the task manager but nothing happens, even after waiting for a while. There doesn't seem to be any CPU, GPU or HDD activity. I have to kill the task to end it.

PC specs:
CPU: AMD Ryzen 7 5800X3D
RAM: 32GB
GPU: GeForce RTX 3070
MB: ASUS TUF GAMING B550-PLUS
PSU: Corsair RM750x
OS: Windows 10 French
Game installed on HDD via GOG Galaxy.

GPU and Chipset drivers are up to date.
I tried rebooting, reinstalled the game, reinstalled GOG Galaxy, ran the game as administrator. added the game's folder to Windows Defender's exclusions.
I tried the fix mentioned in the FAQ (removing GOG Galaxy and galaxy.dll) but it doesn't work. galaxy.dll isn't there, I tried removing Galaxy64.dll but the game won't launch without it.
Both DX11 and DX12 versions have the problem.

Were you using any mods? If you do, keep in mind that a lot of mods won't work with the remastered version.
