When searching for the error, you find yaml/pyyaml#724. The solution to the problem in this case is to use version 6.0.1 of pyyaml instead of 6.0.0.

A quick fix would be to adjust the requirements.txt file accordingly. However, it seems reasonable to also take the PRs from the Renovate BOT into account.
