I'm trying to reproduce what you mention of the End of log printed early but I can't reproduce that, I tried 3 sideloaded games and that always happens at the end

One issue I noticed with this is that it doesn't really print the launch command, it prints the executable and arguments only. So for a native game this is fine, but for a game using wine/proton this doesn't really show the actual command? for the different stores we print more data also like env variables for example
