'Content Decoding error on my website when I add a UTM to the URL

I set up an ad campaign for my website and added a UTM to the links. So far so good. The problem is, everytime I enter to said link and reload the page I get one of the following errors in the console:

Failed to load resource: net::ERR_CONTENT_DECODING_FAILED
---
GET https://example.com/?utm=test 200

Also, the loading times are way slower. Without the UTM I never had any issues with the loading of my website.

Any Ideas of what could be causing this? The website runs on wordpess.
