Display: Automatically adjust brightness - Not working anymore after running Parallels

Hi guys,

I tried Parallels yesterday (Windows 11 ARM) and had a blast. Amazing installation process and everything worked beautifully. I could run games on it without issue.

At one point I realized that my Mac Display Setting - "Automatically adjust brightness" doesn't work anymore.
Restarting my Mac didn't help, shutting down Parallels didn't help.

In the end I reset my Mac (I just bought it so it was no hassle at all) and now everything works again as expected.

I am wondering if anyone else experienced this before?

I love Parallels and want to continue using it, hope there is a fix!
