Hey there! I believe this is because the building was turned off by script. There is a mechanic in the mod where the main computer will turn itself off if the pollution on the planet becomes too high.
Sadly I do not speak your language, but I believe that in one of your screenshots next to the red dot it says "disabled by script". If that is the case then indeed the pollution on the planet is too high, removing pollution will make the building work again and this is intended behavior. If that is not the problem please let me know and I will take another look.
I understand that there is currently only english localization for the mod and some of the mechanics might be unintuitive or hard to understand, I apologize for the inconvenience. Eneas has alot of text so adding additional locale is going to be alot of work, but if there is growing interest I will definitely add it eventually.
Thank you for the report and thank you for checking out the mod!
