Please fill in the template, the template is there for a reason. What version of Moving Elevators are you using? When did the crash occur, what are the steps to reproduce it?

As far as I can tell, this crash has nothing to do with Moving Elevators. It appears the crash is caused by a mixin to RenderType failing. Moving Elevators does not mixin into RenderType.
The real cause is likely printed earlier in the log. Could you share the logs/latest.log rather than just the crash log?
Does the crash go away if you disable Moving Elevators?

The crash seems to be due to Sodium. This should now be fixed in Moving Elevators version 1.0.8.
Thank you for reporting the issue!
