It’s important to take into consideration @TG2’s suggestion as bounce rate could be affected by page load time, however I’d imagine this is due to the expectation of visitors after clicking on the ads. What’s the CTA you use? Also, why are you requiring another click before visitors can do what you’re sending them to do (see if they qualify)?
For every additional click you require from your users you’re going to see a drop-off, and depending on your ad copy, your users may expect to see something more informative. For example, if your ad says something along the lines of “See if you qualify with our 30 second survey!” and they are greeted with another page stating the same thing, they’re probably not going to engage. If instead you brought them to a page that includes some additional information about average savings alongside the survey questions, they may be more enticed to stick around and fill out the form.
I’d recommend testing some alternate versions with more valuable information and no extra clicks (outside of submitting the form) to see if that helps out. While there are some added requests and additional page weight added due to the font bug mentioned above, I don’t see any evidence of that causing concern within Lighthouse:
