[!] xcodebuild -showBuildSettings timed out after 4 retries with a base timeout of 3. You can override the base timeout value with the environment variable FASTLANE_XCODEBUILD_SETTINGS_TIMEOUT, and the number of retries with the environment variable FASTLANE_XCODEBUILD_SETTINGS_RETRIES
Preparing credentials for target '__eas_build_default_target__'
The above line in logs suggest that you are using an older version of eas-cli, in the past, we couldn’t detect the target name correctly, build with the latest cli at least will show that target in logs. It’s likely not an issue here, but it’s worth a try.
It’s possible that this step just take a bit longer, so you can try increasing the timeout or/and number of retries via env variables (you can define them in eas.json)
