Paradox launcher crash

[Flux]

Hello I think something is wrong with the paradox launcher for Linux and MacOS. It will crash, launch another instance, then crash again. my libva is up-to-date on my Linux distro and running Nvidia driver 535. Paradox forums report crashes as well but do not give any info that I've found below:

On Linux:
Remove the following files and folders:

~/.var/app/com.valvesoftware.Steam/.paradoxlauncher
~/.var/app/com.valvesoftware.Steam/.local/share/Paradox Interactive/launcher-v2
~/.var/app/com.valvesoftware.Steam/.local/share/Paradox Interactive/launcherpath


Then when you load the launcher, DON'T click "SKIP" or "Get Started" -- just wait to see if it crashes or updates. You'll probably see a flash in the top right that it's restarting to apply update. If that doesn't work, hit "Get Started" next time you launch and then wait. If still not working, launching over and over (without deleting the folders or clicking skip/get_started).

Only the 2nd time I've had to do this, and it wasn't the same process (but was the exact same problem)

Hope this helps.

Have the same error with the launcher on NixOS. It worked fine a few months ago but now the launcher crashes after a few seconds, restarts and crashes again. I don't have this filestructure (missing the com.valve.....). Any confirmation if this workes at least?

My install was via flatpak. file structure may vary if you installed via package manager (I don't know?).

OK found it! It's exactly inside the path mentioned in this article, thank you. Launcher also works now. However I get a LD_Preload-Error. I'll keep investigating.

Edit: Steam was missing the ncurses6 library (either didn't detect it or it wasn't installed). I added the following overlay to my configuration.nix:

(steam.override {
extraPkgs = pkgs: [ ncurses6 ]; <--- ncurses6 inside!
})
