Thanks
pd: just a quick update. I created a new user just to try out if there was any relation between initial set up failure and inability to install epic game store. So on with this new (empty) user when i first started lutris, it ran the initial setup and completed all downloads and then epic game store installed without any problem. So there is a relation between first run setup and epic game store. Naturally it is not an option for me to use that empty user on a daily basis as I would need to move all my other stuff to that user that is almost impossible and would require lots of work. So I would be really happy to be able either to re run first run setup or to remove all setup files and directories to reinstall lutris.
