How can I animate a car going forward with geo cached characters in it for animated short? (video included)

This is my first UE project and this is for a rendered animation, not a game. I come from the world of Maya and C4D and i’ve always wanted to try out UE5 but now I’m super stressed, i’ve spent 4 days working on just getting everything into UE. Now that I have everything setup, I’m having a very hard time trying to figure out how to simply animate the car with the geocache characters. I don’t need anything fancy at all - rotate tires, car moves forward while the characters animate, some nice camera work, render, done. I’m so stuck.

Here is quick video showing what i’m trying to do and why it isn’t working: Dropbox

I added my GeoCacheActors and the car components (StaticMeshActors) to a blueprint, this was recommended by chat GPT so I could simply animate the car. However, when I push Play, while the geo caches play, the car disappears and I get this error:
AttachTo: '/Game/UEDPIE_0_MB_Miami_Beach_Day_2.MB_Miami_Beach_Day_2:PersistentLevel.BP_Car2_C_0.StaticMeshActor_2127' is not static (in blueprint "BP_Car2"), cannot attach '/Game/UEDPIE_0_MB_Miami_Beach_Day_2.MB_Miami_Beach_Day_2:PersistentLevel.StaticMeshActor_2127_GEN_VARIABLE_StaticMeshActor_CAT_1.StaticMeshComponent0' which is static to it. Aborting.

ChatGPT said the error was because some of the objects in my BP are set to static - i checked, they are all set to movable.

Also, when I put everything in the blueprint, it removed it from the outliner - how can i bring the objects back without reimporting everything?

I’m at a bit of a loss here and I’m not even sure what questions to ask at this point. I didn’t think doing a super simple animation would need to be so complicated. I’m used to being able to parent objects in an outliner and animate properties. I’ve watched dozens of youtube videos and read through so many help docs. What should I be doing?

Here’s a screenshot of what i’m working on as well.

It’s so simple in Maya/C4D. Parent the character roots to the car group and translate it forward, add keyframes. What is the right workflow to do this in UE?
