The Desktop app is not Opening

I have installed - uninstalled - reinstalled rive, for windows 10 but it is not opening. Tried the method found in forum mentioned below.

1) Launch the Windows "Add or remove programs" console and use that to remove/uninstall the Rive app.

2) Launch Powershell and choose "run as administrator"

3) In Powershell, type get-appxpackage -allusers -name riveeditor | select name, packagefullname and hit Return.

4) That command should list all of the installed versions of the Rive application. If there are any instances still listed after running Step 1, this may be a problem.

5) If there are any instances of the Rive app still listed, you can attempt to remove them by typing Remove-AppxPackage -package fullPackageName where fullPackageName should be something like com.flutter.riveeditor_1.8.1704.1691_x64__g2vzrvmhnrrvc (from Step 3).

6) If Step 5 succeeds, install the latest Rive app from https://rive.app/downloads, and see if the problem was resolved.

Please guide me, What could be the problem?
