I'm seeing the same on a few of my projects, for example:

Thanks. I'm not able to help with the error message - @humitos should be able to - but I wonder if the message could be improved. Would this be less cryptic?

"There was a problem with Read the Docs while building your documentation. This is most likely a problem with our system, not with you! If you would like to report this, please do so here (https://github.com/rtfd/readthedocs.org/issues/) and use this build ID number: 833292002"

This is most likely related to #3985.

As we learn how to catch more of these errors, the plan is to make these less general. This is a problem with RTD though, so there is no way for a normal user to remedy this, hence the generic error. We'll investigate on our side, but most likely related to bugfix release 2.3.9 and others from last week.

Opened #3999 to deal with this, I'm rolling all the reports up there.
