Fixed in: 10.33.4, 11.0.7

Safe to downgrade to: a release before 11.0.0

1. Check installed version

npm ls pnpm

2. UPGRADE to 10.33.4

npm install pnpm@">=10.33.4"

3. If no update is available yet, DOWNGRADE to a release before 11.0.0

npm view pnpm versions npm install pnpm@"<11.0.0"

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.

After downgrade

Restart the service, and keep the package held until a fixed release ships.
