Gradle - aapt2.exe unsigned

I am using Gradle 9.4.1. in Android studio, Windows 11

I get a windows error that aapt2.exe is unsigned. (unknown publisher)

Is there a signed version of aapt2.exe?

aapt2.exe is something that the Android Gradle Plugin uses.
It is not really related to Gradle itself.
And afair even AGP just uses it, but it is part of the Android SDK, so you might want to move this question to some Android community.
