Fatal error on setuid Flatpak installations

[Samuil1337]

Dear Flathubbers,

When I try to run Anki using flatpak run net.ankiweb.Anki, I get this error message.

Preparing to run...
Qt warning: setHighDpiScaleFactorRoundingPolicy must be called before creating the QGuiApplication instance 
2025-01-27 21:10:26,250:INFO:aqt.mediasrv: Serving on http://127.0.0.1:45727
[3:18:0127/211026.295800:FATAL:flatpak_sandbox.cc(289)] Your Flatpak installation is setuid, which is not supported

I am on Arch Linux and have set the kernel.unprivileged_userns_clone = 0 sysctl parameter for security reasons. This means that I have to use bubblewrap-suid which might be causing this issue. However, this doesn't happen with any other Flatpak app. Additionaly, it's important to point out that the sandboxing shouldn't really have trouble in this particular instance. Anki is just a chill QT application.

Yours sincerely,

I am also experiencing this, Anki being the only app affected.

I am able to get around this with the non-Flatpak release, but this wasn't the case in some previous versions which had an indirect dependency on systemd(I'm on Slackware)
