No.  If this platform is important to you, please consider setting up a
Nightly dashboard submission [1].  Inspecting the code, I do not see the
issue.  The symbol appears to be created [2] with the correct exports [3].
 Maybe a dashboard submission will show details that will help us work
together to fix the issue.

If we can get issue fixed, we would be happy to coordinate with you and get
4.5.2 released in later in March before your release.
