Under the pinned topic OPC UA implementations (Stacks and sample applications), there is a GitHub repo listed for Ansi C. The link returns a 404. It was working not too long ago. It seems to have been removed recently.

That also applies to this topic: Ansi C source client example. A user was looking for a client example and was pointed to a sample publisher. This also gives a 404 when it was working a few months ago.

What happened to the Ansi C repo?

It was taken offline because of vulnerabilities that were not going to be fixed.

An open source alternative can be found here: https://open62541.org/

Note that the open62541 is not managed by the OPC Foundation.

Was there an announcement that contains information on what these vulnerabilities were?

All that were reported before the codebase was taken offline were fixed in the code.

The concern was more about new vulnerabilities.
