Feature Update 1809 - 2019-06C Causing Bitlocker Issues

Question
-
Has anyone else experienced computers getting the 2019-06C Feature Update causing their workstations to prompt for bitlocker keys? We've also experienced a few corrupt EFI after this update as well? Right now I've only confirmed this issue for Feature update to windows 10, version 1809 x64 2019-06C.
For most of the users, once we get Bitlocker back in, they seem to be doing okay. I can't find anything on the feature update as to what is being upgraded or if this is a known issue.

Hi,
Thanks for your reply.
If there is any response about this issue from Microsoft, I will post here asap.
It's recommended to upgrade to 1903, the latest version, to keep your machine up-to-date.
Best regards,

Hi,
There is no such issue reported by Microsoft.
Did you check the symptom in 1903? We could upgrade to 1903 the latest version to check the issue.
Besdies, we can use Windows 10 built-in feedback hub (type feedback hub in search box) to give Microsoft a valuable feedback and I am going to submit this case to Microsoft via our channel.
Best regards,
Yilia
