We are looking to understand the system requirements of the Windows version of Collector Classic and if there are any needed Antivirus/Endpoint security exclusions needed from a Microsoft Intune/Microsoft Defender perspective.
ArcGIS Collector Classic for Windows Freezes on Start/Login Release 20.0.1
There appears to be a frequent issue that our field users are experiencing with Collector on Windows with the app freezing on startup. Users are forced to wait for upwards of 20 minutes for the app to start up. The user experiences a "White Screen" where all you see is an entirely white app. There is also the same delay when switching from Portal to AGOL, but again only on the initial login for each.
