Export breaks to parts plugin not working

Hey all,

In the past I have used the 'export breaks to parts' plugin but it is currently not working on Musescore 4. I tried all three versions from this post here independently:

https://musescore.org/en/project/export-layout-breaks-parts

When I run the plug in, nothing happens. I have tried exporting breaks from the score as well as individual parts.

I also notice than when add

As far as I know I have the latest version on Musescore 4 though I'm not sure how to check. When updates are added I generally download them.

I'm writing a music book for my beginning band class and this would save me a ton of time.

Thanks!
Jordan
