Android studio error: Process 'command 'python'' finished with non-zero exit value 1

[ejonathanlindgr]

I have been developing successfully for months on my OculusGO. But then suddenly yesterday, when I was building my project, it failed with the error message

Process 'command 'python'' finished with non-zero exit value 1

I had not done anything, not changed any code, not updated Android Studio. I reinstalled Android Studio, but I still get this error message, even when I try to build the VrCubeWorldNativeActivity sample. I am really lost here. (The full error log can be found in my stackoverflow question https://stackoverflow.com/questions/55787482/android-studio-process-command-python-finished-with-non... )

Does anyone know how to solve this problem? Only thing I have not tried now is to wipe clean my harddrive and reinstall everything, but I would like to avoid that

Android studio version is 3.4 (after updating), Mobile SDK version 1.18 (also tried on the latest version 1.22, where I first got the error message "Task 'assemble' not found in root project 'OculusRoot'.", which was solved by changing my gradle version from ~5 to 4.10. after that, I get the same error message described in this post)

perhaps this post should be move to Mobile development?

After further research, the error happens in VrApp.gradle, when it runs the ovrbuild_sdklibs.py.

I found a solution, posted it on my stackoverflow question if anyone is interested
