Endless loading with WordPress 6.5.2

[erossini]

I have a blog that I have just updated to the version 6.5.2 of WordPress 6.5.2. In my blog, I use the plugin SyntaxHighlighter 3.7.0. After the WordPress update, the version 3.x of the plugin has some issues: the browser can't render the page properly and as a result there is a endless loading.

In the following video, I recorded the behaviours.

I am planning to upgrade my site to Wordpress 6.5.x.
Is it verified that in this case Jetpack Boost is the reason for SyntaxHighlighter Evolved is not working/loading?
Is SyntaxHighlighter Evolved working with 6.5.x in general?
