macOS, 12.7.5 (21H1222)
3.3 (3324)
Not sure what happened. It stopped working this week.
What exactly isn’t working? Does it display code like in Sequoia? QuickLook finder preview not working properly
I can confirm this. I installed an macOS update last night and it doesn’t work since then. I’m investigating.
The interesting thing is that OP is on macOS 12.7.5, which is a much older version.
Did I just get “no u”'d for calling your macOS version old? 
I get the same, and have been for a long time. Some days it works, some days it doesn’t.

Ok I realised quicklook is broken across all my files after all.
