Blocked due to plan-no-user-seats-available

Receiving this error immediately when the workflow starts, but only when the workflow starts as a result of the Renovate bot creating a pull request. When a regular user creates a pull request this error does not happen. Any suggestions?

Also worth noting that we pay for 4x parallelism (not the free plan).

Update: this randomly stopped happening and builds started working again.
