All software installed via flatpak cannot be opened!

[Felicia]

All software installed via flatpak cannot be opened!
I use the debian template. After I updated the template, all flatpak software cannot be run by clicking the icon or command line. Error content: bwrap: Can’t mount proc on /newroot/proc: Operation not permitted
zsh: exit 1

You had the same issue before, how did you solve it then?

After updating debian all flatpak software can't be opened!

After updating the debian-12-xfce template, all flatpak packages cannot be opened, and attempts to update flatpak and uninstall and reinstall are ineffective. Error: bwrap: Can’t mount proc on /newroot/proc: Operation not permitted error: ldconfig failed, exit status 256 zsh: exit 1 flatpak run org.telegram.desktop.

I installed one app image to personal (Debian with kernel 6.6.36-1) yesterday and it worked fine (no sudo was required). I uninstalled it since because I discovered binary package works better for me.

Btw, I don’t use zsh. I use bash.
