I have the Windows 10 1903 update installed. Since then xojo hangs when creating web app in the step Linking. In the other post, I read it to try a new Windows profile. But this did not work. Under new profile I had to re-activate xojo - remaining activation 0 :(
After restoring to Windows 10 1809, everything is back to normal.
Is there a solution to perform the build process on Windows 10 1903?
