Hey there!

Is this a package you knowingly installed or perhaps came as a dependency when you installed URP?

if you aren’t sure, could you attach your project manifest? We should be able to identify if it’s a URP dependency or not based on if there’s a specific entry for com.unity.searcher in the manifest or not.

The manifest can be found here: Unity - Manual: Project manifest

Just ran into this issue. Can I just disable the searcher?
