Oh yup, I had same issue. Landed on beach, no NPCs or enemies, couldn't save, hitting F5 for quick save told me that mid-dialogue save was not functional yet, could not interact with ladders or doors, I could hear people in what I guess will be a town but could not see them.
Started new game since loading my previous saves did not work, and on the new game file I got the cut scene before the beach. Now it also lets me save from menu.
I had opened up a thread here, with Larian support, and in Steam, before seeing this =/
