Incorrect installation of NDK: Unity 2019.3.2f1
In new versions of Unity (such as 2019.*.*), you need to download Unity Hub and then install Unity and other necessary tools from there. Here I installed the Android SDK, NDK, and some other tools. The problem is that during the installation, the Internet was disconnected and at this point the SDK was installed, but there is no NDK. Then the download was cut off and NDK remained on the island as they say. The check mark in Unity Hub is worth it and it can not be removed in any way.
But Unity itself sees that there is no NDK and forces you to install it.
There is always an option to reinstall Unity, but it is not a fact that this will not happen again during the download.
So is there any other way to install the NDK, or how to remove this check mark in Unity Hub, so that you can try to download it again?
