Miltech Hub 1.3.2 - Steam Installed - Crashes FS2024

Hi, I recently updated to 1.3.2 from the old ver 1.1.0

I can create a mission, and I can "SAVE & PLAY" once ... if in the mission I decide to edit it, and then hit "SAVE & PLAY" it freezes after 1 min crashes .. and the I have to "STOP" the game from the "STOP" or kill button in Steam and start again. Any insights !
