After noticing I was posting my issue in a similar but not same topic I prefer to create a new one.
I have a workspace with different test suite pipelines and from time to time randomly one or more of the TCs failed due to the same error.
Could not start a new session. Response code 500. Message: An unknown server-side error occurred while processing the command. Original error: Cannot start the 'com.nemergent.client.mcptt' application. Consider checking the driver's troubleshooting documentation. Original error: Error executing adbExec. Original error: 'Command '/opt/android-sdk/platform-tools/adb -P 5037 -s A75359FRCN94HDV01CC shell am start -W -n com.android.project/com.android.project.MainScreen-S -a android.intent.action.MAIN -c android.intent.category.LAUNCHER -f 0x10200000' timed out after 20000ms'. Try to increase the 20000ms adb execution timeout represented by 'adbExecTimeout' capability
Before asking it. All the TC have the exact same configuration and environment. The devices are always the same and never fail the same TCs.

First, I agree that this is a different issue and thanks for opening a
new topic, which is appropriate.
Second, here is the troubleshooting documentation for uiautomator2 driver:
Third, I think you forgot to attach the log. I will go over when you attach.
