Please always attach a simple .blend file which demonstrates the issue, even if the steps seems simple.

I can not reproduce the issue, but in such a dependency cycle situation is hard to guarantee proper evaluation order, or to reproduce a wrong evaluation order to reproduce the crash. For until the cycle is solved will be impossible to solve the crash. And other way around: with the cycle solved the crash should be gone.

This is the same root of the issue as #57589.
