I would agree pretty much with you, but OP posted this 13 hours ago. In ten hours only one person replied and only had a similiar issue about one of the points.
Kubuntu is no a popular distro of choice within the gaming space so i doubt it will easy to find someone who can help to troubleshoot their problem. Also i think i read somewhere that Ubuntu had some problems with 32 bit libraries. I may be wrong tho.
As i replied on another comment, changing distro will probably be the fastest way to solve or at least diagnostic the problem. It’s probably extreme but better than nothing. I would also try the flatpak version first.


This! Good advice! I went this path last year so i can give some extra advice for everyone who wants to start:
Before doing anything, buy a new router and put your iot devices and phones in a isolated guest network. Maintain the router updated. After that, you can work, learn and test without fear. Everything stays in your home.
Then like @[email protected] already said, once you get confident, you can run a vpn tunnel to access your lan. This setup is pretty robust, hard to fuck up, and doable even for newbies. (If i can do it, everyone can, i assure you). Lots of guides out there.
Last advice, which you should already be doing, but setup a backup.
