Fix Clipboard Copy Operation Crash

Fixes a COM exception crash related to clipboard copy events from changes in Avalonia 11.3

Solves [Ryubing/Issues#294](https://github.com/Ryubing/Issues/issues/294) caused by Avalonia 11.3's changes, see [AvaloniaUI/Avalonia#20007](https://github.com/AvaloniaUI/Avalonia/issues/20007) for more information

I've only tested this on Windows, no idea if this has issues in MacOS or Linux, or if it's even a problem there at all.
