https://ufile.io/2bt1i the save file if it will help debug... I updated the mods and now it's not playable anymore. :(((

Seems to be not compatible with nanobots: Early bots mod. It's the only one I updated and error disappears when mod is disabled.

yep having the exact same issue, tried deleting and reinstalling the mod and still did not work.

I get this error as well after updating Nanobots. Disabling nanobots removes the error message. Look for file "mod-list.json" in Appdata/Roaming/Factorio folder and edit the file to say enabled: false instead of enabled: true

does this allow you to play with both mods? is there anyway to go back a version with nanobots?

Sure, just replace the nanobots-???.zip file with a prior one. You'll find the prior ones under nanobot's and downloads. https://mods.factorio.com/mod/Nanobots/downloads
