Overview
This is a temporary workaround for sites experiencing any issues with WordPress 6.9’s new ability to load block styles on demand in classic themes, for example #64354.
If running a classic theme (i.e. not a block theme), it filters should_load_separate_core_block_assets to be false. This has the effect of reverting a change introduced in 6.9 where classic themes now load separate core block assets on demand by default.
Note that this plugin should be considered temporary until any issues are resolved in 6.9.1. At any time, you can test whether any issues remain by adding ?should_load_separate_core_block_assets=true to any frontend URL; this restores the default behavior in WP 6.9.

Great plugin, issue still not resolved in 6.9.1

This workaround fixed the issue on my site, kudos to the developer. However, even after 6.9.1 the issue is not resolved without this plugin. Other users report the same, so now not sure how to get a permanent resolution. Surely, WordPress are aware of this?!
This really helped!

Fixed broken layouts after upgrading to WordPress 6.9
by chrisandrew·3 months ago
We built and maintain a hybrid classic/headless WordPress website for a national client. A number of our frontend components (CoreButton, CoreMediaText, etc.) tap into WordPress core editor classnames, props, and critically, CSS rulesets, to provide our client the flexibility they expect when editing blocks and posts.
After updating to WordPress 6.9, these components failed to render as expected. Our investigation led us to the post on wordpress-6-9-hotfixes, and subsequently, this plugin. Thankfully, installing this plugin resolved the issue.
Thanks to @westonruter for taking the time to publish this hot-fix.
