The second thing I saw is about an app sandbox being used, but using a sandbox with any app like Sigil is simply not a good idea. Not sure is adding the option to turn off the sandbox would help or not.
I found 3 vulkan related packages for your system:
vulkan-tools
vulkan-utils
mesa-vulkan-drivers
That last one is key.
Please make sure all 3 are installed on your system and if not present install-them.
Next try running this command to see what graphics card you have and which driver it uses:
lspci -k | grep -i VGA
Please let us know what you find.

I'm not sure about my graphics card and vulkan - (there is a much longer story about the graphics card).
It looks like the sandbox is responsible for the long initial startup time. Not a major problem, but I'll look into the link you provided in your following post.
I have the following vulkan packages installed:
libvulkan-dev
mesa-vulkan-drivers
vulkan-tools
vulkan-tools is described as 'miscellaneous vulkan utilities'
vulkan-utils is not listed as an available package, but there is a package 'vulkan-utility-libraries-dev', although not installed.
lspci -k | grep -i VGA gives the following result:
