Same of SteamOS with flatpak Heroic however I've done a bit more digging.

It seems there is a 403 forbidden error when trying to download from Epic Games.
I've attached the legendary log from trying to install Overcooked 2 but below is the important bit.

Log location:
/home/deck/.var/app/com.heroicgameslauncher.hgl/config/heroic/GamesConfig/Potoo.log

This makes me think Epic has changed something which has broken legendary

derrod/legendary#479

This issue on legendary suggests Legendary has already fixed it, the updated legendary package just hasn't been upstreamed yet

[DEAD1SIDE]

I tried to login in lutris to try it there but there the library doesn't load and icon to login still appears. So the probability that it is on epics side is high i would say.
