Multiple assets are overridden to use the same GUID: 06883681e19214d79b0ad9d0e2ac8e8e
Assets/Editor/AdMob/SDK/GoogleMobileAds.framework/Headers/GADNativeCustomTemplateAd.h
Assets/Editor/AdMob/SDK/GoogleMobileAds.framework/Versions/Current/Headers/GADNativeCustomTemplateAd.h

I came across with same problem and my solution is that uncheck “PlayerSettings/Other Settings/ Metal Editor Support” toggle from Windows.

BOMB. ANYONE could help ?

if you’re using admob, for us the issue was in assets/plugins/ios from there remove the googleMobileAds framework and it should work.

Hi everyone, i fund a miracle solution about this bug
i espect this will work for you as for me, and that will help unity to correct the problem…

when this happens,

  • open photoshop
  • open explorer
  • drag an image to photoshop
  • go back to unity and it should focus again to it.
