404 error on every page

when crawling our site we get a 404 error on every page where the WP Call button is shown. The path is:
<link rel=’stylesheet’ id=’wp-call-btn-guten-blocks-style-css’ href=’https://bcfgj.com/wp-content/plugins/wp-call-button/assets/block/build/index.css?ver=0.97843900%201727364883‘ media=’all’ />

When browsing the file structure of the plugin – index.css file does exist but is located at the path:
https://bcfgj.com/wp-content/plugins/wp-call-button/assets/block/build/build/index.css

I can edit the code but would like this to be checked/fixed in future plug-in updates.
