Getting error on unity

so im trying to build an android ar game in unity 2021.3.5f1 and i am getting this error when i go to build it.
it say to come here for help. any suggestions?

The hint to ask here unfortunately comes for any failed Gradle build which imho makes no sense at all. You seem to have some problem with your content, but you didn’t even post what the console the screenshot hints at displays. But you are most probably better helped in some unity community.
