Codeball action takes ~5 minutes to run

[Sebelino]

The Codeball action normally takes less than 30 seconds to run. Starting today, however, I noticed it started to take over 5 minutes to run and contains the line

Waiting for job 93352b5d-eabe-4581-81e9-b1ce1ca81c34 to complete... (1/60)
[...]

repeated 60 times. This appears to be happening consistently, for all 5 jobs that ran in my repository today, and all repositories I have checked.
