Error updating the Android SDK 29

In Google Play, when downloading the apk file, it writes:

Change the Api target level 28 to 29

I go to Unity -> in player settings -> I change the checkboxes to API 29.

When building a project, it displays a message on the screen:

Update the Android SDK 29?

I click update, then I get an error:

Try installing it manually by specifying the path to sdkmanager.bat

I write the path in the command line:

C:\Program Files\Unity\Hub\Editor\2020.1.2f1\Editor\Data\PlaybackEngines\AndroidPlayer\SDK\tools\bin>sdkmanager.bat "platforms;android-29"

Then I agree with the license.

And then there is such an error:

Accept? (y/N): y
Warning: Failed to read or create install properties file.
