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-43543-to-queued_ltr_backports
# Cherry-pick the merged commit of this pull request and resolve the conflicts
git cherry-pick d290df292f49d3accaf2e16296d83928d92c1c49,eb7d465c42278cb2ebb79812c467e344e8c30868,572995889a5c2e08cf8dacd40dd95a7d66b66add,65a50af5d4cf91877e4425a3956c1e0a999c0366,155fd5c79bb724581b8e724b656c1ba58d393f82
# Push it to GitHub
git push --set-upstream origin backport-43543-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-43543-to-queued_ltr_backports.
