What would cause a VST3 to display a Write Problem error?

Hey all! Trying to load RealEight guitars by Musiclab, which I've done before on both PC and Mac. On Mac again, Sonoma. And when I drag it in it says Operation Could Not Be Completed Because Of A Write Problem.

Any ideas? Is this some kind of disk permission thing or something else?

NVM solved it. The plugin (Realeight) was waiting for license activation. Weird that that's the error I got, instead of the plugin displaying but that might be on the plugin dev side.
