Microsoft released an optional Windows 10 update for version 2004 with a number of bug fixes and quality improvements earlier today. This release has addressed two of the known issues affecting Windows 10 May 2020 Update that have blocked some users from upgrading their devices to the latest version.

While both the above problems have been resolved through KB4568831, the company isn't removing the compatibility hold on the affected devices since this is an optional update and not bundled with Windows 10 v2004, which means some devices could still be open to problems. Microsoft said that it expects to remove the associated safeguard holds in mid-August, when the Patch Tuesday will make today's fixes a part of the non-optional, security update bundle.
