[2021] Cannot load my save file!

Gentlemen, disaster struck!
My 102 hour playthrough of this fantastic game might be unrecoverable!

I made a save file yesterday at 1:42 am in my local time, ready to head to bed. This morning I tried to load my game and everytime I press continue, it crashes during loading.
If I try to manually load a game, I just hear a click and nothing happens.

I've tried repairing the game multiple times, the game keeps doing this modded or vanilla.
Starting a new modded game however appears to be fine, did my save got corrupted somehow?

I can share my save game and mod list if that helps.
Help would be appreciated!

EDIT: It seems I have found which Autosave still works, I lost around 3 hours of progress and during this time I was mainly developing the Arctic (Autosave is when I just started colonizing my first Gas Island). I cannot load any file after that.
Well at least it's not a terrible a loss, but still, possibly either the Gas Heater mod or the Increase Radius for Gas Pump from Spice it up compilation might be at fault here, weird but possible.
