"An error occurred whilst trying to determine the file version" when trying to create new project in SDL Studio 2019


I've just installed SDL Studio 2019, and I'm getting the above error message when trying to create a brand new project. I've seen related threads here, but I couldn't find a solution for me in any of them, as most of them refer to issues opening already created projects or using old project templates. I'm not doing any of that, I'm just trying to create my first new project in SDL Studio 2019 from scratch.

By the way, the above error message appears as soon as I click on "New Project", so I can't even get to the new project wizard window.

Any ideas? Thanks in advance!

Kind Regards,
