Iso not mounting

I am running KDE. I am trying to mount ISO. But it does nothing.

If I run lsblk. It shows me loop0 device. But dolphin file manager does nothing.
any solution? I am trying to mount ISO by gui not from terminal.
I tried gnomedisktool. It results same. loop0 device shows up. But nothing happens.

❯ lsblk -f

Very often - such issues are caused by a missing reboot after a kernel update - please reboot and try again.

I have tried rebooting.

In that case I have no idea.

Manjaro usually has no problems with mounting an ISO so if it is not a reboot after kernel update?

Stupid question I know - but is your system fully up-to-date?

E.g. the konsole returns a message stating nothing to do when you run

sudo pacman -Syu

I have updated the kernel last week. My system is up to date.

Maybe try with Acetoneiso2
