i can send you a savegame with the mods and/or also the mods config
-this problems locks many other researches and makes my modpack unplayable
Thank you for helping.

That weird I will check, it only required 1 tech before but it dont available to research maybe it require another hidden tech

Checked, it working fine for me

maybe you can send me the save file i will check so i can point you to what mod cause the problem
or you can update all the mod you use it maybe fix

Sure , here is the save file:

Should directly download tha save file
*The pack is on 0.17.49 atm.

Wow that a lot of mod my game didnt ever start

Hmm, for me it works, i even stoped using the Rampat Mod ailiens because they tend to use 5-9gb of Ram Alone.... . I am currently Not at Home, maybe i can give you my Steam or discord Account Name and we can Look at the Problem later together If you want... (my discord Name: Neko14789 #4530)

I have updated my modpack to 0.17.50, the moduls research is still not working :(
Here is a map again https://drive.google.com/file/d/11ZADXwcVSyyoh_40czKo-VajZKoWK3dD/view?usp=sharing
for me the loading with save-mod-synced worked on an seperated game instance.
*factorio peaks at about 3 gb of ram usage while loading
-sorry for bothering you but i don't know to figure out the error myself..

little that I know there are several config in these mod Bob's modules, AAI Industry, Circuit Processing are causing this issue.

Hm, i removed the Circuit Processing mod because after reviewing my modpack it doesn't fit in with the bobs modules, but like you said removing it didn't help with the error, seems like there still are conflicts

So without the AAI Industris mod it works...
