Microsoft has released a new build for the fast ring insiders, build 18922. A few new changes in this build, and a few known issues (similar to previous builds).

Known Issues

This update might fail the first time you try to download it with a 0xc0000409 error code.
For Home editions, some devices might not be able to see the “download progress %” change on the Windows Update page.
There has been an issue with older versions of anti-cheat software used with games where after updating to the latest 19H1 Insider Preview builds may cause PCs to experience crashes. We are working with partners on getting their software updated with a fix, and most games have released patches to prevent PCs from experiencing this issue. To minimize the chance of running into this issue, please make sure you are running the latest version of your games before attempting to update the operating system. We are also working with anti-cheat and game developers to resolve similar issues that may arise with the 20H1 Insider Preview builds and will work to minimize the likelihood of these issues in the future.
Some Realtek SD card readers are not functioning properly. We are investigating the issue.
Tamper Protection may be turned off in Windows Security after updating to this build. You can turn it back on. In August, Tamper Protection will return to being on by default for all Insiders.
We’re investigating an issue where some users are reporting that File Explorer search is rendering in an unexpectedly small area and clicking it results in a crash.
