Im facing same issue.
Let me ask you are you using plugins like FSR Mobile / Optional Mobile Features Blueprint Library.
I faced same errors. it occures at any mobile project with c++ codes in it.
solution was simple, just run this file and wait.
“C:\Program Files\Epic Games\UE_5.6\Engine\Extras\Android\SetupAndroid.bat”
I tried running the setup android.bat file and mine says

Android Studio SDK Path: C:\Users\adonnelly\AppData\Local\Android\Sdk
Using sdkmanager: C:\Users\adonnelly\AppData\Local\Android\Sdk\cmdline-tools\latest\bin\sdkmanager.bat
