Heroic Games Launcher stuck on "loading" screen after update

[fruchesi]

Hey community,

I installed Heroic Games Launcher during December 2025 using Debian 13, and it run perfectly. I used it only with my GoG account. Nevertheless, I updated to the last version (2.21.0-linux-amd64) during March, and it stopped working properly. As the title of this post says, it is stuck on the "loading" screen, without displaying anything. I tried a couple of solutions but none got the app working (I deleted the folders heroic and legendary at .config, for example). If I delete those folders and start the launcher using a terminal, I can see the interface again, but the buttons do not work if I click them.

This is what the terminal shows when I run heroic from there:

Could you please help me revert this? I have tried Lutris and it work really well with some games, but I have difficulty running others after installation. This is my first post here and I while I am not new to Linux, I just have experience as a desktop user (almost 0 dev skills but I can manage to solve things following instructions). Thank you very much in advance.

UPDATE: It seems I was able to solve it, finally. Adding --disable-gpu to the command worked pretty well.

I have found the solution here:
