Fedora 44 KDE Prerelease: Flatpak crashes when starting "Heroic Games Launcher"

denalb · March 1, 2026, 1:49pm

Yesterday I installed the prerelease version of Fedora 44 KDE. Sometimes I get KDE crashes on Fedora 43 KDE and want to try out if the crashes also appear on Fedora 44 KDE. Until now there wasn’t any KDE crash.

Fedora 44 KDE runs good. I got all my packages, codecs, and drivers installed. No issues in general. I also installed some Flatpaks, like “Betterbird”, “ProtonPlus”, “Ferdium”, “XnView MP” and “VueScan” and have no issues with them.

Actually, there is one issue. When trying to start the Flatpak version of “Heroic Games Launcher”, Flatpak crashes with the following error.

The question is, if this is an issue with the prerelease of Fedora 44 KDE, an issue with Flatpak in general, or an issue with the Flatpak version of “Heroic Games Launcher”?

Any advice from you?

pg-tips · March 1, 2026, 1:57pm

On Fedora 43 KDE with the latest Flatpak version of HGL, I don’t see this issue.

So it could well be a Fedora 44 issue. Although my GPU is Nvidia where yours is AMD, so that’s another potential avenue.

denalb · March 1, 2026, 2:13pm

Yes. I also didn’t have an issue on Fedora 43 KDE with “Heroic".

pg-tips · March 1, 2026, 2:14pm

Right, so that probably rules out a couple of possibilities:

anothermindbomb · March 1, 2026, 2:15pm

Reading from the bottom up:

                #2  0x00007f11dec877b3 abort (libc.so.6 + 0x17b3)
                #3  0x00007f11df96b480 g_assertion_message.cold (libglib-2.0.so.0 + 0x2480)
                #4  0x00007f11df9d8917 g_assertion_message_expr (libglib-2.0.so.0 + 0x6f917)
                #5  0x00005631e89ed2e3 flatpak_permissions_to_strv (/usr/bin/flatpak + 0x8c2e3)
                #6  0x00005631e89f2216 flatpak_context_save_metadata (/usr/bin/flatpak + 0x91216)
                #7  0x00005631e8a5f0c6 flatpak_run_add_app_info_args (/usr/bin/flatpak + 0xfe0c6)
                #8  0x00005631e89cf681 flatpak_builtin_run (/usr/bin/flatpak + 0x6e681)
                #9  0x00005631e898cd9b main (/usr/bin/flatpak + 0x2bd9b)

Main starts, does some “add_app_info” stuff and then tries to save context (presumably the stuff it’s just built in “add_app_info”). This triggers a check (or a set, I can’t tell) of some permissions which fails an assertion and causes the SIGABRT.

Maybe it’s setting up the default screen res, or whatever this launcher wants to retain across runs.

It looks like a permissions issue, but what and where, I cannot tell. We’d need the core dump for that.

denalb · March 1, 2026, 2:43pm

How can I get that?

anothermindbomb · March 1, 2026, 2:46pm

coredumpctl

man coredumpctl for the gory details, although it’s not that horrific to retrieve one from the repository.

denalb · March 1, 2026, 2:51pm

Tried $ coredumpctl info 5266 in the terminal and got the same output that I posted above.

What exactly do you need?

anothermindbomb · March 1, 2026, 2:59pm

You would export the core with the -o flag… like so:

coredumpctl -o wibble.dump dump /usr/bin/spectacle

That will produce a file named wibble.dump in the current directory which would then be analysed with a debugger, such as gdb or lldb

┌─🎩 lurcher ~
├─
└─➜ ls -al *.dump                                                                                                                                                                                                 14:51 Sun 01-Mar
Permissions Size User  Date Modified Name
.rw-r--r--@ 174M steve  1 Mar 14:49  wibble.dump

As you can see, they are of a reasonable size.

denalb · March 1, 2026, 3:18pm

Ok. Got that. Created the dump file from the latest crash.

https://cloud.dennisalbrecht.de/s/WiNyf8djLiSAeGx

Maybe someone can read that dump file and could see a detailed crash log?

Also, I removed an overwrite I did for getting access to mouse cursors and gtk3 folder.

flatpak --user override --filesystem=/home/$USER/.icons/:ro && flatpak --user override --filesystem=/usr/share/icons/:ro
flatpak --user override --filesystem=xdg-config/gtk-3.0:ro

Now the output in the terminal looks different.

$ flatpak run com.heroicgameslauncher.hgl
[13 preload-host-spawn-strategy] Failed to let stub process know of exit: Ungültiger Dateideskriptor (errno 9)

I don’t know if this helps.

grumpey · March 1, 2026, 5:43pm

Have you tried resetting all your overrides/permissions?

denalb · March 1, 2026, 7:16pm

Yes. I removed them from all Flatpaks. It didn’t help.

denalb · March 5, 2026, 2:08pm

It looks like it could be an issue with Heroic Games Launcher. Other users on Bazzite also have issues with starting the launcher.

reinstalling but had no luck. I asked in the Fedora Discussion community already because I wanted to know if this is an issue with Heroic, Flatpak or the prerelease version of Fedora 44 KDE. Until now there is no solution. Heroic is the only Flatpak that makes trouble. All other Flatpaks I'm using, like “Betterbird”, “ProtonPlus”, “Ferdium”, “XnView MP” and “VueScan” are working well. Is this an issue with Heroic?

I went back to Fedora 43 KDE because there are some repositories that are not available for F44 yet. Also I installed Heroic Games Launcher as an RPM from Copr and it works great.

Let’s wait for the release of Fedora 44. Hopefully Heroic Games Launcher is working then.

Interesting, I don’t think Bazzite would have taken the Fedora 44 changes (they’re normally more or less in line with released Fedora), so I wonder what’s going on there. Thanks for raising and linking the issue, let’s see what emerges!

hi,
it’s not about heroic launcher imo, i’ve found that io.github.Faugus.faugus-launcher crashes the same way. probably something with fedora’s flatpak 1.17.2 package went wrong. I have the same issue on any devel silverblue/workstation.
If I force dowgrade flatpak to 1.16.3-f43, everything works again.

I‘m using Faugus as an RPM from Copr repository maintained by the developer. That’s why I didn’t recognize it.

Same issue on beta. It works unisolated, with: --no-sandbox
