flatpak on musl/arm64: error: unable to allocate instance id

[akrmn24]

I am getting this error when trying to run a package I installed for flatpak from flathhub. Tried org.chromium.Chromium and org.gimp.GIMP and they both give this error. Anyone else tried this on this architecture/libc?

I ended up just using the backend utility (bubblewrap) to do what I want, and with Firefox. I built Firefox in a glibc chroot, then I binded certain directories there with bwrap (and set the environment variables and X server access) and ran it. Should be similar for chromium.
