Current behavior?

I have been receiving this message when trying to save a variety of tensorflow models since version 2.11. I have reported it before.

It appears to be produced by the lack of an ability by tensorfow to serialize the model representations it maintains in memory.

TypeError: Unable to serialize 64.0 to JSON. Unrecognized type <class 'tensorflow.python.framework.ops.EagerTensor'>.

See the debugger output below for details

Can I change anything in my models to dodge this logic?
Is there another model saving function I can try?

Standalone code to reproduce the issue

Please email me for code.
