Announcing Windows 10 Insider Preview Build 18945

"Hello Windows Insiders, today we’re releasing Windows 10 Insider Preview Build 18945 (20H1) to Windows Insiders in the Fast ring. If you are one of the few Insiders who accidentally received Build 18947 earlier this week, see this forum post where we recommend you rollback to the previous build and then update to today’s build to be on the best path forward."
