launchApp no longer works while Maestro Studio is open since update 1.37.0

[pplourde]

Is there an existing issue for this?

• I have searched the existing issues and didn't find mine.

Steps to reproduce

1. Ensure that Maestro Studio is running and Maestro CLI was updated to version 1.37.0 or higher
2. Run any flow that includes the '- launchApp' command

Actual results

• App closes and doesn't relaunch.
• Test fails as the app does not launch while Maestro Studio is open.

Expected results

• App closes and relaunches.
• Test passes and continues as normal.

About app

• Issue is encountered regardless of the app used to test. The command is broken and does not work if Maestro Studio is running even when attempting to launch well known app such as Youtube or others.

About environment

• Issue was reproduced across multiple Android devices (found on S22 Ultra Android 14, reproduced on S20 Android 12, Pixel 7 Pro Android 14)
• We did not attempt to reproduce on iOS so issue might or might not occur with iOS.

Maestro version

1.37.9

How did you install Maestro?

install script (https://get.maestro.mobile.dev)

Anything else?

• Closing Maestro Studio and running the same flow again works no problem.
• Flow will always fail while attempting to do - launchApp while Maestro Studio is running.
• We had no issue at all prior to updating to the 1.37.0 (or higher) versions of Maestro CLI.
• Since issue can occur with any app, logs included are running Maestro Studio while attempting to launch Youtube app using - launchApp command.

Hey @pplourde, can you show exact commands you used, and also the flow file?

My repro

I reproduce this issue, but with different logs/errors. I'm curious why's that. This is my flow:

# file: samples/android-flow.yaml
appId: org.wikipedia
---
- launchApp:
    clearState: true
- tapOn: CONTINUE

• wikipedia app is, of course, installed on my Android emulator
• Maestro v1.37.9

First I run:

maestro studio

Then in a new terminal tab:

maestro test samples/android-flow.yaml

Terminal logs:

$ maestro test samples/android-flow.yaml
\
Running on emulator-5554

 ║
 ║  > Flow
 ║
 ║    ❌  Launch app "org.wikipedia" with clear state
 ║    🔲 Tap on "CONTINUE"
 ║

Unable to launch app org.wikipedia: null

Additionally, I also tested on iOS and there's a different bug – Maestro Studio stops working, i.e. the emulator screenshot stops refreshing.

repro:
0. Run iOS simulator (I used iOS 17.5)
0. maestro download-samples

1. maestro studio
2. in a new tab maestro test samples/ios-flow.yaml

studio logs

$ maestro studio
Running on iPhone 15 - iOS 17.5 - BCFE83EE-F9A2-4612-B7B4-4CB05CE2406B

Tip: Maestro Studio can now run simultaneously alongside other Maestro CLI commands!
