Solved Transparency effects / Mica not working

I just installed Windows 11 on another PC today and got a visual reminder that Transparency effects / Mica aren't working on my main PC at all. The new PC that I installed Windows 11 onto, it works fine. I did some Googling and tried some different solutions out, but no luck at all.

I discovered MicaForEveryone, and was hoping that it might be a magical solution. However, I couldn't even get it to run at all. Do you guys have any ideas? Thanks.

SmartSystemMenu/https://github.com/AlexanderPro/SmartSystemMenu/ has options:transparency and aeroglass.I use it in Windows 11 Home-it is very good.

Thanks. I gave it a shot but it doesn't seem to make any change to transparency at all. Also, it seems to make Firefox very sluggish and unable to load websites for whatever reason. Very strange. I like the ability to assign a button to close windows though.

Okay. So it turns out I solved the problem. 0fficialKUBA's post in the Reddit thread did the trick:
