Could not switch to resumed project ${resumedCwd} (${error i

Error message

Could not switch to resumed project ${resumedCwd} (${error instanceof Error ? error.message : String(error)}); failed to restore launch directory ${launchCwd}: ${rollbackError instanceof Error ? rollbackError.message : String(rollbackError)}

What it means

switchToResumedProject chdirs into the resumed session's project and reloads settings; if that fails it rolls back to the launch directory. When both the switch AND the rollback fail (rollback includes restoring plugin roots and activeSettings.reloadForCwd), it throws a SessionResolutionError combining the original error and the rollback error.

Solutions

1. Read the two embedded messages: fix the resumedCwd problem first (recreate the directory or pick a session whose project exists).
2. Fix the launch directory problem (cd to an existing directory before launching omp).
3. Check settings files in both directories are readable/valid JSON.
4. Verify filesystem permissions on both project paths.

Example fix

// before
cd /old/deleted/project && omp --resume <id-of-session-in-also-deleted-dir>
// after
cd /existing/project && omp --resume <id>

import * as fsSync from "node:fs";
if (!fsSync.existsSync(launchCwd) || !fsSync.existsSync(resumedCwd)) {
  console.error("Both launch and resume project dirs must exist before resuming across projects.");
}

try {
  await resumeAcrossProjects(...);
} catch (err) {
  if (err.message.startsWith("Could not switch to resumed project")) {
    // parse both parenthesized causes and fix paths/settings before retrying
  }
}

When it happens

Trigger: Resuming a session from another project where (a) chdir/preload into resumedCwd failed (deleted dir, permissions), and (b) restoration of launchCwd also failed (launch dir deleted, settings reload threw).

Common situations: Both the original and target project directories were moved/renamed/deleted between sessions; permission changes on project folders; settings file corruption making reloadForCwd throw during rollback.
