The code block works fine in the past. However, there is an user created a new post with code block yesterday, and I found the format failed. Not only this post with block code, but also whole site.
I just rebuild discourse app to the most update version, but the result is still the same.
How can I solve this issue? Thanks for help.

The code blocks look fine to me, do you have a screenshot of the code block format failing?

Thanks for great input.
However, it seems meta discourse forum is version 2.9.0.beta6(cause it support “Loading splash screen” now). And the code block works fine here.

My Solution
1. uninstall component “hljs-theme-picker”
2. pick up the one css file ( I picked up rainbow.css) from the below
> **[hljs-theme-picker/assets at main · discourse/hljs-theme-picker](https://github.com/discourse/hljs-theme-picker/tree/main/assets)**
>
> main/assets
1. edit theme CSS/HTML, copy and paste contents in rainbow.css
This is wrong???

Many thanks to Takanobu san.
This solution works fine.
I think this means discourse hljs theme picker has some hidden bug. No reason the same code works fine with CSS but failed on component installed.
And I’m sorry that I will not set your solusion as ✅ Soluion, though it truly solve my problem. I leave it as open and hope discourse team @cocococosti can find out the reason behind and work out a formal solution.
The CSS code I use is what I set in hljs theme picker:

Many thanks again.
