It appears to be from the uncode theme, perhaps some customization done, or an intended update. The file names are static, but the query string is changing on every pageview.
Take a look via google chrome dev tools, under the network tab.
For example, these files (https://i.imgur.com/Y5fohtZ.png
)
/wp-content/themes/uncode/library/js/init.js?ver=375711253
/wp-content/themes/uncode/library/js/plugins.js?ver=375711253
/wp-content/themes/uncode/library/js/app.js?ver=375711253
the query string (375711253) change on every pageview (just refresh and you can see it). https://i.imgur.com/65rE5re.png

The query string changing will not only prevent any minification from doing the intended optimization for these files (the minification always sees a different, new file) but it also prevents browser caching for those files (even without minification).
I suggest checking with your dev or perhaps the theme author (if it’s the original theme) on why they need dynamic query strings on those static files. Version numbers should be ideally tied to the plugin/theme version, not some random or other digit.
Thanks
