I am following this tutorial (https://experienceleague.adobe.com/docs/experience-manager-learn/forms/creating-your-first-adaptive-...) and using the visual editor or the code editor does not save any of the rules that were made. I looked for others with the same issue and have tried changing browsers from Chrome to Edge, restarting the instance but no luck.
I have the following packages with AEM 6.5.0:
adobe-aemfd.win-pkg-6.0334
AEM-Forms-6.5.4.0-WIN-6.0.138
aem-service-package-6.5.8
core.wcm.components.all-2.15.2
