How to cancel PrintPreviewControl print when exception occurs after selecting locked file

[BreyerW]

This is about printing to file like print to pdf and the like.

My problem is that when user selects locked file through SaveFileDialog-like window PrintDocument.Print() throws Win32Exception. I catch it and present error dialog to the user. User accepts it and..... application hangs despite swallowing exception.

Is there a workaround for this issue? Tried putting Print() in BackgroundWorker so that i can kill it in catch clause but doesnt work since that access UI object in separate from UI thread. Tried making custom PrintController but achieving quality parity with previous code turned out to be very problematic.

Note: i dont mind using unsafe or reflection if thats what it takes to handle this specific scenario

Thanks in advance

EDIT: ah i forgot to mention that i use legacy WinForms on .NET Framework 4.8 if that affects available solutions.
