Comment:

 Sorry, but the project you provide is too complex and I'm spending too
 much time trying to debug this. Reopen if you can put together a more
 minimal project that reproduces the problem and hopefully also bisect to
 find the commit where things changed. Thanks!

Comment:

 Can you try to put together a minimal sample project to reproduce the
 crash and [https://docs.djangoproject.com/en/dev//internals/contributing
 /triaging-tickets/#bisecting-a-regression bisect] to determine where the
 behavior changed?
