Cannot toggle checkboxes and switch control in system settings

Question

I encountered recently \dev\mapper\elementary--vg--root error because I encountered BSOD in my host machine. I fixed the issue through fsck /f.

When I boot up again my VM, the startup wizard where this displays after the installation, popups again. I tried to turn off some settings through the wizard and also through system settings but the setting always reverted.

I added a gif image showing the issue.

Did you boot in recovery mode? It looks like your root volume was likely mounted read-only. Can you remount it read/write with the following command?

sudo mount -o remount,rw /

For the error IO charset iso8859-1 not found, try booting into recovery mode and running depmod as this AskUbuntu answer mentions.
