Comment 2 for bug 1852007

Same error as above but I'm not trying to add grub background pic. In my case, I'm re-ordering the boot menu. (Default to Windows 10 with MX Linux 19 below instead of vice versa) Attached is a screenshot of the error message. I can provide any further info needed to diagnose this but I need to know what is required. I have used grub-customizer many times before on many different distros with never a problem. This one is perplexing.

grub-customizer version: 5.1.0-1

MX Linux: Linux MX19 4.19.0-6-amd64 #1 SMP Debian 4.19.67-2+deb10u2 (2019-11-11) x86_64 GNU/Linux
