Description
Describe the bug
Managed Debugging Assistant 'PInvokeStackImbalance' : 'A call to PInvoke function 'Wpf.Ui!Wpf.Ui.Interop.User32::SetWindowLong' has unbalanced the stack. This is likely because the managed PInvoke signature does not match the unmanaged target signature. Check that the calling convention and parameters of the PInvoke signature match the target unmanaged signature.'

Research direction
Start by locating the PInvoke declaration for User32::SetWindowLong referenced in the report and compare it with the unmanaged target signature, including calling convention and parameters. Reproduce the launch under the debugger on Windows 11 with .NET 4.7.2; done when the PInvokeStackImbalance warning no longer occurs and the app launches normally.
