No snapshot builds since Nov 19

I noticed that there has been no new snapshots since November 19:

https://oss.sonatype.org/content/repositories/snapshots/dev/zio/zio-prelude_2.13/
https://oss.sonatype.org/content/repositories/snapshots/dev/zio/zio-prelude_2.12/

In my initial investigation, I also noticed that Github actions have been failing lately. Not sure if this is related to the snapshot publishing issue, as this issue seems to start occurring even before RC8 was released. It appears builds consistently failed at the autoupdate / autoupdate (push) task. Here's an example:

PR-786 seems to be the culprit and causes the following error:
