Error starting Evolution installed as flatpak

HI All
I switched Evolution from Ubuntu to flatpak source, but when I try start flatpk evolution I get the following error; ‘error: opendir(/): Permission denied’.
I have used the -vv switch the last 3 lines of messages are;
F: Allowing wayland access
F: Allowing pulseaudio access
error: opendir(/): Permission denied

On the Evolution forum , it was suggested I install another component (Calendar) which I did , but same result
F: Will ensure existence of directory: /home/gc
F: Converting FlatpakExports to bwrap arguments…
F: “/home/gc” is meant to be a directory
F: Ensuring “/home/gc” is created as a directory
F: “/home/gc/.local/share/flatpak” is meant to be a tmpfs or empty directory
F: Parent of “/home/gc/.local/share/flatpak” is not mapped, creating empty directory
F: “/home/gc/.var/app” is meant to be a tmpfs or empty directory
F: Parent of “/home/gc/.var/app” is not mapped, creating empty directory
F: “/home/gc/.var/app/org.gnome.Calendar” is meant to be shared (ro or rw) with the container
F: Allowing wayland access
error: opendir(/): Permission denied

as per the Evolution forum , the App should not need access to Root (if opendir(/): is Root).

How do I get more debug information from flatpak?
Thanks
