Hello Pealik,
We regret the inconvenience this causes, and we get that many customers rely on the deployment feature. We have been working on a fix which will be made available later this week. We are finalizing and testing the build now.
It will be made available on our update page with a beta label because we want to get confirmation from customers first for a few fixes that are in there.
Please keep an eye on the page below the coming days. The release will be 12.1. As said it will be listed as a beta release, but it is a full release, QA approved.
We hope that with this release, you will get your deployments running again.
