Bugs in content types

We got this issue with Image paring memory game module after updating WP Core to 6.9, this is immedietly fixed after rollback. We also have the latest version of H5P on our site.
Attached are screenshot of the issue. On the screenshot, the memory game is not working at all, not even hidden plus the layout is broken. The other screenshot is how it should look like.

To me this looks as if either

  1. the CSS file is not loaded - you should find hints to that in your browser's development console/the network tab (see https://snordian.de/2024/02/17/how-can-i-craft-an-effective-bug-report-for-h5p-components/)
  2. the content types stylesheet is overwritten by local CSS changes (MemoryGame does not run inside an iframe and therefore is sensible to the CSS of WordPress that may have changed with the latest WordPress update or with the theme).

Thanks for the comment! We are still having this issues and looks like multiple CSS files are not loading. Uploaded is the working and the not working versions. On the not working versions only 2 CSS is loading. Other that this no console issues found

Adding this code fixes the CSS loading issue 

add_filter( 'should_load_separate_core_block_assets', '__return_false', 100 );
