When can we expect a working version of Reality Composer that runs on iOS / iPadOS 14?

Currently experiencing a crash when opening Reality Composer on two iPads running iPad OS.

further info: version 1.4 on Lidar iPad, and on 9.7 iPad Pro; both are running iOS 14. Crash even if selecting the Plus to create new rcproject...
Had hoped the 2nd beta might fix this, but no luck.
