Erm, forgive my curiosity, but if your game crashes at the new game screen, how did you get a save in the campaign?
I don't know. This save from Tales of the Sword Coast. And this save already present after installation. Maybe developers put this save to play directly in Tales of The Sword Coast? (This is addon for original Baldur's Gate)
Anyway. Load this save = crash.
Anyway, to address your actual issue, first you need to state exactly where your game is installed to, and if it has full administrative rights. The game need to do some initialising when you first play it, and if your installation locations is preventing this (a Windows 10 thing?), this may explain the crashes.
Install into D:/Galaxy/Games/Baldurs Gate
baldur.exe have full administrative rights. I tried to establish compatibility mode with Windows 98/XP but this is not help. And i add baldur.exe to Windows Firewall exсeptions. And crash, and crash, and crash...and so on.
At the evening i try to intall english version (now Russian). Probably it will help.
Before that i install in D:/Galaxy/Games Icewind Dale and complete all game without any troubles.
