I cannot run the game. When trying to start from GOG Galaxy or download, i get the following error

"Adventure game studio:
Loading game failed with error:
Script link failed: Runtime error: unresolved import.
'AGS2Client::SetAchievementAchieved^1'.

The game files may be incompete, corrupt or from unsupported version of AGS.


Looking for a solution, please fix this.
Thanks.
