This bug was documented in 2021:
https://support.esri.com/en-us/knowledge-base/error-the-selected-template-can-t-be-loaded-000024906
Is this still the only solution to this issue? I do not have administrator privileges, nor the ability to constantly move templates back and forth. This is happening constantly with various report templates and our only solution is to rebuild them every single time. For such a pricey extension, this is an extremely frustrating bug. Is there any way to identify WHY the reports won't load? Is it a bug with the way the reports are set up?
