Install the latest updater. If that doesn't work, replace RPG_RT.exe with the latest version.
If it still crashes, use the Unofficial extended version, which is an improved version of the original. Unofficial may be deleted depending on the antivirus.
Use of Unofficial is at your own risk. Pass:326126 https://k00.fr/rybwf9m7
