Potential fix for https://github.com/ChristianRosewich/CSharp/security/code-scanning/5572
To fix this safely without changing intended functionality, update the null guard around
ubgTso dereferencing only happens whenubgTis not null.Best single fix in
GenFreeWin/GenFreeWin/Gen_FreeWin/ViewModels/PersonenViewModel.cs:Delete(), changeif (ubgT == null)toif (ubgT != null).Count,string.Join, confirmation dialog), so behavior remains the same for valid returned collections while preventing null dereference.No new imports, methods, or dependencies are required.
