GitHub is moving ubuntu-latest to Ubuntu 26.04 (Oct 19 - Nov 19 2026). With DISPLAY unset, WDIO 9 spawns each worker through xvfb-run, and 26.04's xvfb-run closes fd 3 - the worker's IPC channel - so every worker dies with "write EINVAL" on its first process.send (webdriverio/webdriverio#15685, fixed upstream in 9.33.1). The suite drives an Android emulator through Appium and never needs a virtual display, so turn the wrapper off instead of bumping WDIO. Checked locally with DISPLAY unset: main's config logs shouldRun=true, this config logs shouldRun=false and forks the worker directly. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
