are you using Heroic lsuncher from flatpak? if yes you need to somehow add firejail to Heroic app, or just restrict acess to internet for whole Heroic launcher flatpak --user override --unshare=network com.heroicgameslauncher.hgl

if not you need to add firejail wrapper with --noprofile --net=none args without any quotes (it says “Make sure to quote args with spaces”, which is not your case)

I’ve never used the Heroic launcher, but I think the “wrapper command” is what you need

in lutris no, it will automatically launch as ${COMMAND_PREFIX} ${WINE} ${EXECUTABLE}

yes, … is path to .exe, and yes I also has similar problems with some games with default wine

but for gaming I use lutris with proton, and using firejail from lutris has better results for me (almost all games works without issues)

[SomeGame] > Configure > System options > Command prefix > firejail --noprofile --net=none --

firejail --noprofile --net=none -- wine ...

i use https://dev.yorhel.nl/ncdu for this

maybe this can help you
