Missing Resources error on new campaign tracks

[uneven dome]

can you go to the main menu and take a screenshot of the version in the bottom left?

it should be 202312180944-202312212350
if it's something different, you're not on the latest version and might not be able to play the latest campaign maps
if your version is fine, you'll probably want to report your issue to the devs directly (see ?bugreport)
