Hello! I think this issue might be similar to another one. Can you try the fix I mentioned in #402 (comment)?

Long story short, the support on Windows platforms does not seem consistent over all Python and Qt versions…

[almahmoud-phys]

Thanks Jérome, it is working now

[TommyLITommy]

Hi Jérome, I saw the examples on your manim-slides website, so how did you embeded the slides on the web?

Hi @TommyLITommy, thanks for your question! However, this is not an appropriate place to ask questions, especially as it has nothing to do with this issue. I have opened (and answered) a discussion for this: #487.
