Anyone here having issues launching Flatpaks?

I’m having trouble launching Flatpaks (v 1.12.7) on my workstation (KDE Neon 22.04)

Here’s the repair output:

$ sudo flatpak repair --reinstall-all

And when I try to open Edge:

I don’t understand how I’m getting a R/O filesystem when my Snaps & Debs are perfectly fine.

My laptop and desktop at home (Kubuntu 23.04) and my work VM (Rocky Linux 9 with Flatpak 1.12.5) are perfectly fine.

It appears to have been caused by NoMachine, which is odd since I have a Rocky Linux 9 VM that also has NoMachine and that’s fine.

Seems to be a known issue.
