After updating to 4.41 I can not create new users without

After updating to 4.41 I can not create new users without getting a blank page that needs to be refreshed. After refreshing the user exists and can log in. It takes about 30 secs prior to hanging and turning blank. When I run a debug I only see warnings and no fatal error. I have tried deactivating all plugins and changing themes. My test environment updated and works fine. Any ideas?
