Hello, just installed the new v2.3.8965 and it fails to launch, displaying a broken-looking dialog with the error "Critical Error occurred in WinNUT".

I'm on Windows 11 23H2, build 22631.3880, with .NET framework 4.8.09032. The Windows event log shows event ID 1000 (Application Error), with the following diagnostic information:

Faulting application name: WinNUT-Client.exe, version: 2.3.8965.28008, time stamp: 0x66996e11
