In addition to user.config, the folder contains another file named a2rx2s4u.newcfg. The user running the application has full control on the folder.

The application is run on a Windows 2019 Server with Citrix XenApp.

I've logged the activity of the app with Sysinternals Process Monitor. As far as I understand, the application tries to rename a2rx2s4u.newcfg to user.config replacing the existing user.config, and that seems to fail:

Unfortunately, I don't have a 32-bit Windows at hand, and as the application is x86, Process Explorer cannot resolve symbols.

It might be interesting that the stack trace contains "Sfrhook.dll" which is the "Citrix Special Folder Hook DLL". I think this DLL implements Special Folder Redirection in Citrix.

According to the Windows Error Codes reference, the error code 0xC0000369 means STATUS_INVALID_DEVICE_OBJECT_PARAMETER:

The device object parameter is either not a valid device object or is not attached to the volume that is specified by the file name.

I do not understand this - the source and the target of the rename is in the same directory.

How to further narrow down this problem?

[EDIT1] The user profile seems to reside in an FSLogix profile container: https://docs.microsoft.com/en-us/fslogix/configure-profile-container-tutorial

When using Profile Container, both applications and users see the profile as if it's located on the local drive.

[EDIT2] We now have another customer which experiences the same problem. This time: No Citrix, but "Windows 10 Enterprise multi-session" - also uses FSLogix Profile Containers. https://docs.microsoft.com/en-us/azure/virtual-desktop/windows-10-multisession-faq

We have found that in server 2019 it required the UAC virtualization setting needed to be disabled for user level writes. Using Process Monitor, we found that when the error occurred, it wrote to a UAC event log. For legacy applications this issue occurs when the user.config file is being copied from the "user.newcfg" file that is just a temporary file the the .NET code creates.
