Problem with creating internal flow volume

I have made a new version with the simplified cylindrical batteries and have also removed the clamp holes at the top, but I am still getting interference errors and I cannot resolve them through “Fix interferences” since it would just end up processing for hours and not change or allow me to exit it.

Is there any solution to this problem as I really need to get this simulation running as soon as possible to get results for my project.
