Error Removing deployment: Problem processing request

Hello all! I'm getting the error Error Removing deployment: Problem processing request trying to remove a deployment (I noticed it because after a recent push to GitHub I ended up with 2 running deployments instead of the usual single one). I managed to remove the most recent deployment but I need to remove the other one (and after that I will redeploy the updated version), how can I sort this out? The project ID is f6d25e17-9bb2-457f-8ce2-e55b5ce1dcd8
