UE4 not launching after creating a new project

Hi!. I just download UE4 (4.25), installed and everything went ok. Because my primary disk is a small SSD, I change the installation directory to my second internal HD (D:/). I’m not sure if that’s the reason but UE starts fine, I select the category, the type the name of the new project, but the it starts initializing, it hangs at 39% and stays there, not going forward. Any idea about what could be causing this? I’m stuck here.

Thanks in advance

just wait while it s compiling shaders for your project.
it can take time depending on your computer.

Thank you, you were right, the first time takes some time.
