I'm having a similar issue to LegionTanqolRenfield and Nomad48.
The drop menus are not appearing for hull and class selection are not appearing. Almost everything is missing from the components tab menus as well. Only the items under the upgrades menu is accessible.
However, loading a pre-made saved ship loads some data and displays it properly. But, none of the non-upgrade assets are accessible via the menus, so they can't be modified. The components' of a loaded ship will show up and can be clicked on to view the details.
I have tried running the app as admin and that didn't help. I don't think its a permissions issue. I'm using windows 11 home; the older version I was using was running fine, so I don't think its an issues with the default handling of the csv files either.
the CSV files that have loaded are: Backgrounds, Names, Upgrades
the CSV files that have NOT loaded are: Components, Hulls, StrikeCraft, Torpedoes, Weapons
