Only homepage breaking

Hi, my homepage layout appears to have broken and I can't figure out the fix. Other archive pages that use the identical styling Elements look fine, it's only the homepage that's affected.

I've cleared and deactivated WPRocket and Cloudflare caching for several hours, with no effect. I also made no changes to either of them in the days leading up to this issue.

I've tried deactivating and reactivating all plugins, and the layout shift reappeared as soon as I reactivated only GP Premium by itself.

Any help would be much appreciated, thanks!

FOLLOW UP: While playing around with some settings I found the GenerateBlocks "Regenerate CSS Files" option. Upon clicking this, the homepage loads properly again. According to the GenereateBlocks documentation, changing the CSS Print Method from External File to Inline Embedding should interfere less with caching/performance plugins, so I'll give that a go for now.
