Bug: seems non-JSON serializable values interfere with inspector operation

[aryzing]

XState version

XState version 5

Description

Seems that when using non-JSON serializable values within a machine the inspector @statelyai/inspect stops updating its UI or showing values in its explorer. For example, a fromPromise that returns a BigInt will "crash" the inspector UI and it will not update when the promise completes, even if the internal machine state did transition.

Expected result

Was expecting the inspector to be capable of handling all values.

May not be worth the effort to add support for more value types, although would definitely help if this constraint was documented (if it isn't already? I couldn't find it).

Actual result

No reactive UI updates after the machine processes a non-JSON serializable value.

Reproduction
