I tried to install eclipse EE on top of regular eclipse downloaded through ubuntu store - after the installation eclipse won't open.

tried installing eclipse ee through .deb, "An error has occurred. See the log file /home/v/Downloads/eclipse/configuration/1631686693143.log." error is produced, I tried deleting .metadata from workspace, no use.

Don't ubuntu 20.04 users use Eclipse EE?

Sequence of steps and errors
