The backport to queued_ltr_backports failed:

The process '/usr/bin/git' failed with exit code 1

To backport manually, run these commands in your terminal:

# Fetch latest updates from GitHub
git fetch
# Create a new working tree
git worktree add .worktrees/backport-queued_ltr_backports queued_ltr_backports
# Navigate to the new working tree
cd .worktrees/backport-queued_ltr_backports
# Create a new branch
git switch --create backport-45521-to-queued_ltr_backports
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick 96808065a45747a64235db17649be26b5d23f321,ce2d58d0a78ca76776fb2c9c30f88397356a7df5,6f8bed820b3e50076f308d3e426a871dafc364f9,96187b20c562442d254d907928eb2c1d9bfc9d46
# Push it to GitHub
git push --set-upstream origin backport-45521-to-queued_ltr_backports
# Go back to the original working tree
cd ../..
# Delete the working tree
git worktree remove .worktrees/backport-queued_ltr_backports

Then, create a pull request where the base branch is queued_ltr_backports and the compare/head branch is backport-45521-to-queued_ltr_backports.
