This one works for me after trying trillions of times xD
Make a new project in 5.5 , Games- Blank , name it something like “TestCineware69” no need to change anything else on this page.
Once the project is opened, Do not do anything, Do not create any Map or check any plugins, The very first thing you do is to import the C4D file. Its dumb as fk but it works only for the very first time. It doesnt work after that. Once you import the file you can then turn on any plugins you need or maybe need to make new maps, you can do that.
I Installed Cineware for unreal 5.5 BTW
