I worked on StudioX 10 hours ago and I did not get a notification that anything was about to change. All I saw was that UiPath was uninstalled and I had to reinstall.
maybe the antivirus or any security policy?
As per the latest release (20.4) -
The 20.4 release removes the “Preview” label from StudioX, it’s now being made available as a generally available part of the product with the same quality and support we offer for the Studio profile. A lot has changed since the first public preview in our 19.10 fall release.
