Flatpak fails to launch: Unable to find target for this triple (no targets are registered)

[benthetechguy]

Describe the bug
When I try to run the launcher, the window pops up for a split second and disappears as the application crashes.

To Reproduce
Steps to reproduce the behavior:

1. Run flatpak run io.mrarm.mcpelauncher
2. See window pop up and instantly close with nothing but two errors and a warning in the console (see below).

Expected behavior
I expected the launcher to start like it's supposed to.

Screenshots
Console output:

libEGL warning: DRI2: failed to authenticate
Qt: Session management error: Authentication Rejected, reason : None of the authentication protocols specified are supported and host-based authentication failed
Unable to find target for this triple (no targets are registered)

Desktop (please complete the following information):

• OS: Debian 11 GNU/Linux (armhf)
• Version: Can't see the full version name since the program won't launch, flatpak info tells me v0.2.3.
• Installation Type: Flatpak

Additional context
This is a Samsung Chromebook XE303C12 that I have installed Debian on. There's nothing special about the Debian installation other than its architecture of armhf, so I don't see that being much of a problem, but I thought it was worth mentioning. I got the AppImage version to run, but I couldn't get it to load the Google login page, and there were many more errors, about some libraries like libselinux and others.

flatpak armhf is no longer supported, because armhf has been removed from the used flatpak sdk.

See flathub/io.mrarm.mcpelauncher#54 (comment)

Minecraft 1.17.40+ requires launcher version v0.3.0, the armhf flatpak has stopped receiving updates since v0.2.3.

For the appimage it might be due debian 11 armhf:

try this

Thanks, the appimage started working when I added that flag.
