Show system image Error

Hi All,
I customized with vyos 1.3.3 to install some sotfware. after that it work well excpet one thing that show system image .

#show system image
Error parsing GRUB configuration file. Exiting...

I can’t get return or try to delete image.

It is ok to get a brick if it has conflict dependencies/packets.
You can return to previous system if you have other oldest images or have to reinstall.

just only install vyos1.3.3. But I can upgrade it to vyos 1.3.4 but still error there.
