The startup completes at approximately 12:09:32 (about 7 minutes after 12:02:01).

Additional context

• The issue persists even after increasing fs.inotify.max_user_watches from 65536 to 524288
• No AWS_PROFILE environment variable is set
• Multiple large directories exist in the workspace (cervereta-web-redesign, landing-parking, etc.)
• Many "duplicate skill name" warnings appear in logs (skills exist in both ~/.claude/skills and ~/.agents/skills)

Expected behavior

OpenCode Desktop should start within a reasonable timeframe (seconds to ~30 seconds maximum).

Actual behavior

OpenCode Desktop takes approximately 7 minutes to become responsive after launch.

Important update: The issue occurs even with NO MCPs, Skills, or plugins installed. This was tested on a fresh install before any additional configurations were added. The ~7 minute startup time is reproducible without any extensions.

This issue might be a duplicate of existing issues. Please check:

• Opencode hangs at startup if a .git repo is present and inotify user instances run out #16610: Very similar inotify-related startup hang on Ubuntu 24.04 — same file.watcher timeout errors and No space left on device inotify error pattern. The root cause appears to be inotify resource exhaustion causing the file watcher to time out repeatedly before startup completes.
