Go to windows store, click the 3 dots by your account icon thingy, choose updates, check for updates, download 1.8gb outer worlds patch!
this patch seems to sort the "stuck at press any key screen" issue on PC (gamepass /windows store version) ? It tries to connect to Xbox live, the press any key disappears and you're stuck at that screen listening to the music! After patch this issue, for me, is fixed! AND achievements I had unlocked but hadn't received due to bug, have now popped up! Yay!
