Are there any visuals in your Vuo patch? If it's an audio-only project, you might try something like Plogue Bidule instead of Vuo. If it's an audio and video project, can you post your Vuo file so that we can see what's going on?
I installed macOS 11 public beta (Big Sur) for a few... hours (thanks to Time Machine for getting me back to 10.15.6), and there is now a System Preference in macOS 11 where you can set applications to be in a different language than the OS/Finder. So that should take care of this problem.
Edit: I just saw that it's already in macOS 10.15, but it doesn't seem to be working with Vuo.
