Markdown Monster Clipboard Error

I’m getting a strange clipboard error on my Windows 10 workstation when I use Markdown Monster.

Couldn’t save text to clipboard: OpenClipboard Failed (0x800401D0 (CLIPBRD_E_CANT_OPEN))

I wonder if this could be the same error I was having with MarkdownPad 2 before I switched to Markdown Monster.

I haven’t seen this issue in Obsidian, Notepad++, or any of my other markdown supporting editors.

Any suggestions?
