[Windows 10] - Instant crash when offering an alliance (space phase)

Hello,

For unknown reasons my Steam version of Spore:Galactic Adventures instantly crashes in Space phase when I send an alliance offering to AI. This happens whenever, wherever on the AI territory and whatever I do first. I had not this problem some few hours ago where I could easily offer alliances to AI. I'm playing on Windows 10 and I can provide any other informations if needed, thanks for your incomming help.

I know this game is pretty old but if players are still active here it's because some games are timeless masterpieces 🙂
