App crash with Qt 6.8 on ARM

Hello,
I am facing a issue with my app that is on Flathub. It works fine with Qt 6.8 on x86 but arm seems to crash.

This is the app. Install Tenmon on Linux | Flathub

In this test build I reverted to 6.7 and it is working fine.
flatpak install --user https://dl.flathub.org/build-repo/176217/space.nouspiro.tenmon.flatpakref

Is there any way to select different runtime version for arm?

You can try adding the Qt modules to your app’s manifest but it will blow up size, build time and maintenance cost.

Qt 6.9 got released so I tried to make a build with this version. No change and it crash in same way.

Then I tried to compile Qt 6.9 from source and build my app against that. No problem and my application works just fine.

Created a bug report QTreeView with QFileSystemModel crash on Qt 6.8+ on aarch64 (#70) · Issues · Packaging / Flatpak KDE Runtime · GitLab
