@inarihalla Are you playing with any mods or CC in your Mods folder? If so, please start at Broken/Updated Mods (pinned in this forum). If you still have issues after removing and replacing mods (don't forget to delete localthumbcache), see what happens after you drag that folder to your desktop and delete localthumbcache. (Don't save, though! Or test in a new game.)
I already removed all of my mods and tried without them and deleted localthumbcache, but it won't make any difference.
@inarihalla Looks like you might need to post to this older thread: https://answers.ea.com/t5/Bug-Reports/GTW-Can-t-create-wormhole-generator/m-p/10416152/highlight/true#M185740
