Sometimes after an upgrade, you need to invalidate and clear cache.
There are some known issues in 3.2 so also ensure you are not on Kotlin tools
org.jetbrains.kotlin:kotlin-gradle-plugin:1.2.70
as that causes freeze issues as well.
If that doesn’t work, remove your google plugin lines and support libraries, sync and add them again and sync. Sometimes the cache directories just get out of whack.
