I tried out your modpack with a clean save and load order, however i get the following error "Complex_science_pack_Recipes 1.0.9 failed to load due to the index field 'steam-power' (a nil value). Which makes me deactivate that mod, and then it cascades with other mods having to be deactivated.
What if you start a fresh game? Then also errors? Are you only using the mods from my modpack or more/less?
//edit: There are plenty of Bobs/Angels/Artisana Updates today; I double check now if they have any (negativ) influence on my modpack.
//edit: You are right! I can confirm this error and I will fix that.
//edit: I fixed that. But there is also another error popping up due to latest Angel Exploration update: https://mods.factorio.com/mod/science-pack-dependencies/discussion/6586d24df5454e873273b3bd I have to fix that now as well.
