[2023] My backup does not load. Nothing happens when I click on it

Hi everybody, hope someone can help me with my issue,

My main backup no longer launches when I click on it. 

I have 5 games in all that have multiple saves. My other 4 games launch when I click on any save but the main game does not react when I click on it, no matter which save is selected, nothing happens.

Background: I was playing when a windows pop-up appeared telling me I had to make space on my hard drive. I quit the game 30min later and uninstalled some games to make space on my hard drive. Afterwards when I restarted Anno, the problem occurred my save game would not start.

I've already tried uninstalling and reinstalling the game, it doesn't change anything.

Please help me Ubisoft, I have 478 hours of gameplay on this main game
