6 months ago @zepumph @samreid Can you provide insight into what "cannot set state while setting state" means, and what might typically cause this error?
This assertion is in PhetioStateEngine.ts setState, which is the only place in the PhET-iO code base where I find isSettingStateProperty.value = true. So I'm guessing that setState is somehow being called recursively.
/**
* Sets the state from an object that represents the state.
*
* @param state - a json object (not a string) that specifies the values to set
* @param scopeTandem - returns if the given Tandem is in the scope of a (partial) state
*/
public setState( state: FullPhetioState, scopeTandem: Tandem ): void {
assert && assert( !this.isSettingStateProperty.value, 'cannot set state while setting state' );

I've only seen this once in CT, for gases-intro, 5/10/2024, 3:29:53 AM. Note that further down in the message, the error reported in https://github.com/phetsims/gas-properties/issues/239 ("bad holdConstant state") appears.
