[1.1.80] Corrupted save file - crc error in last level.dat

The game reports a corrupted save file. At the time I was saving the game, there was nothing suspicious: I saved the game closed it on the title screen. Unfortately the auto save files are overwritten now. I've tried to look into it:

- the game reports an invalid zip file
- inside the zip file is a crc error on level.dat238
- there is no level.dat236 and level.dat235 - I am not sure if that is a problem?
- level.datmetadata is probably missing? Adding the file from another save file lets factorio viewing the save state
- however, opening the file fails at the very very end: couldn't read from input file. File could be corrupt.

Obvisouly it's true that the file is corrupt, however I wonder if it's possible to fix the save game somehow. 99% of the save state is available. I am not sure how the partioning of the level.dat files works, maybe there is a hope.

Mod list and log is attached. The save file and the "fixed" one that almost finishes loading are here:

Thanks for any help!
