Error: Test instrumentation process crashed. But there is no /files/ directory

Hi all! I get this error
`Test instrumentation process crashed. Check my.long.package.activity#checkQuitDialog.txt for details`
But there is no /files folder in /data/data/androidx.test.orchestrator, only /cache and /cache_code. I run test on the Emulator

Prerequisites:
```
defaultConfig {
...
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
testInstrumentationRunnerArguments clearPackageData: 'true'
}
...
testOptions {

includeAndroidResources = true
returnDefaultValues = true
}
execution 'ANDROIDX_TEST_ORCHESTRATOR'
}

Thanks!

Reproduce the emulator test with the listed AndroidX Test Orchestrator 1.1.1 configuration and inspect the reported checkQuitDialog.txt error. Compare the expected /data/data/androidx.test.orchestrator/files/ path with the available /cache and /cache_code directories; done means identifying the cause of the crash or documenting the missing diagnostic needed to do so.
