Hello there and sorry for the late reply.
This is the first time I’ve been reported this issue regarding CyclicReferenceManager Mismatch Enter/Exit.
Do all your graphs show this Deserialization Error?
Are there any other errors at all in the console when you open Unity/Scene or otherwise? (very important)
Are any of your custom nodes do anything tricky or anything with serialization?
Is sending the project to be a possibility? If so I would be able to help you much faster and would be great!
