Welcome to the forum

Your save works fine with me.
After opening all four valves located in the hanging platforms near the generator Pathira should talk to you (missing in your video) and you have to walk down to take the core.
Then an intermediate sequence should start.

Maybe one of your mods will cause the problem.
Disable / uninstall them one after the other and try again.

complement: also let Steam verify your game.

And basically: be careful with cheats. They can ruin the whole game for you
Often save manually
