Beginning this morning our users received an error message on starting ArcMap 10.8.1 The message below shows while the splash screen is still active and before the app loads. No changes have been made to our systems or the Attribute Assistant Addin. It is version 2019.2.14. Any Ideas as to why this is occurring and how to resolve the error. If we remove the Attribute Assistant, no error is displayed. Attribute Assistant and ArcMap appear to be working normally even after the error is displayed

Second, I went to ESRI do download the current version of Attribute Assistant at http://appsforms.esri.com/products/download/index.cfm?fuseaction=download.main&downloadid=1874. However, the Zip file will not download and an error message is displayed indicating a Network error occurred during download. I have tried this on multiple systems, browsers and networks with the same result.
