From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I don't know Voidlinux but am curious, what GPU are you using? And is your Linux DE using Wayland or X? Nvidia GPU drivers are notorious for having issues with suspend/hibernate/resume. If it's Nvidia you could try tinkering with enabling/disabling the driver options or the suspend/hibernate/resume services.
These should give you some hints:

Unfortunately I don't know what you'd do exactly to recover from a failed hibernate - the thing with hibernate is that the RAM of the running OS was saved to disk so even turning it off completely isn't going to solve that, the whole point of hibernate is to be able to power off completely after all. When you get your system back up you should do some light testing with standby, not hibernate, just to see if there's issues. Or do what I do and never standby/hibernate :P
I've found similar issues with NVidia cards.
A probable cause is bootloader/initrd issues since these need extra initrd support when booting, and a couple of things can go wrong in updates. You could try to chroot into the system and reinstall the kernel, initrd, and graphics driver.
Oh, and hibernate doesn't work with dual-booting Linux distros (it does not leave file systems unmounted), and although grub was once designed to dual- and multiboot distros, dual-booting is problematic today.... I think some (graphics?) driver stuff can get put into the EFI partition where grub updates can step on other distro's feet.
