Android SDK path only work once

I noticed that my android SDK path only work once after I use it for the first time, this happened three times.

One, is when I downloaded the SDK unity hub which work when I tried to build my project for the first time, after that Android SDK not found error occure.

Two, is when after I downloaded Android Studio and set the external tool path to Android Studio SDK, the Android SDK path invalid is gone, but another error came up which is Failed to update android sdk package list, I restarted my unity and then Android SDK not found occure again.

Three, is when after I downloaded sdk tools only (https://dl.google.com/android/repository/tools_r25.2.3-windows.zip?hl=id) and then replaced it with my Android Studio tools, the Android SDK not found is gone, and the Failed to update android sdk package list came again. (https://stackoverflow.com/questions/37313735/unable-to-list-target-platforms-please-make-sure-the-android-sdk-path-is-correc) From this instruction is that what supposed to come is Update Android SDK but mine isnt, so i restarted my unity and Android SDK not found came again.

Currently im using 2019.3.15f1 version, is upgrading unity will probably fix this problem? Or maybe didnt allow unity as administrator has something to do with this?
