Hello, I'm having trouble resuming a saved game. When I try to load the game, the following error message appears: “corrupt map: unknown decorative prototype ID 34936. File has likely been corrupted due to failing hardware.” The previous automatic saves, which are made every 5 minutes, display the same message.
I’m playing on PC via Steam, on the Space Age map with the Stellar Horizons mod.
My game has 526 hours of playtime, and I’d really like to be able to resume it so I don’t lose all those hours of hard work.
Thank you in advance for your help.

You should probably upload that save here so that people can test for themselves and find what's going on

There's unfortunately nothing to test or figure out. The save is corrupt, likely from failing/failed hardware (as the error states).
