i just updating an older version of fedora 41 kde that i had to the most recent version, and when i did, steam wouldnt launch at all, only greeting me with the steamwebhelper not working error, and no buttons to relaunch it fixed the issue. i tried installing from steam website itself, from flathub, and from snap, but all gave me the same issue. this is what the konsole gives me when i launch steam from the konsole with flathub
