I have solve this error with below steps:
Steps:

1. Go to the location of Unity's NDK. In my case it was under /Applications/Unity/Hub/Editor/2020.3.15f2/PlaybackEngines/AndroidPlayer/NDK like in @roberto-donext case. Your location may vary based on OS.
2. Open the source.properties file and look for the NDK version used, for example Pkg.Revision = 21.3.6528147
3. Go to Android Studio and under the SDK manager download the same NDK version unity is using. (Don't forget to check "Show package details" to see a list of all NDK versions.
4. Once the download is complete go to unityLibrary/build.gradle and configure that version inside the top android { }. For example ndkVersion "21.3.6528147"
5. Build
