I’m getting this error (UE4 4.26.2) when building for android devices (specifically my Oculus Quest, but I get the same error when I try building to all android devices). Here’s my log:

I’ve been struggling with issues building for my Quest for several hours; nothing I read has solved my issue. I have my SDK, NDK, and JRE directories explicitly specified in my project settings:
Location of Android SDK (the directory usually contains 'android-sdk-'): C:/Users/[me]/AppData/Local/Android/Sdk
Location of Android NDK (the directory usually contains 'android-ndk-'): C:/Users/[me]/AppData/Local/Android/Sdk/ndk
Location of JAVA (the directory usually contains 'android-ndk-'): C:/Program Files/Android/Android Studio/jre
SDK API Level (specific version, 'latest', or 'matchndk' - see tooltip): latest
NDK API Level (specific version or 'latest' - see tooltip): android-21
I have also tried running the included SetupAndroid.bat and always get the following error log:
Android Studio Path: C:\Program Files\Android\Android Studio

Update failed. Please check the Android Studio install.
I couldn’t find any fixes online to help me with this, but for what it’s worth I made sure that I have all of the correct versions of the platform tools specified on Line 75 from the .bat:
call "%SDKMANAGER%" "platform-tools" "platforms;android-28" "build-tools;28.0.3" "cmake;3.10.2.4988404" "ndk;21.4.7075529"
I would appreciate any help! I haven’t found any answers for this anywhere.
