Timeshift CLI segmentation fault, GUI of timeshift works great.

Hi, I hope that you are doing fine.

This issue first appeared when I tried to use timeshift from the CLI yesterday, I was trying to switch from nvidia and xorg to nouveau with wayland, but I messed up, I had created a backup of timeshift in this case, and when I tried to restore it using a live usb. (yes, I screwed up really good.) But then I got hit with a segmentation fault error. I tried another time (and multiple times after that) and it also gave a message saying "[Warning] Deleted invalid lock". Also I use Syslinux as grub was too slow for me. But it didn't matter if I selected yes or no when it asked about reinstalling grub, it always segfaulted.

Unfortunately I screwed up so bad I had to reinstall arch yesterday. After installing it, I tried using the GUI version provided (when installing timeshift from pacman). It worked flawlessly, the restoration, creation, everything. I also tried creating a snapshot with --create in the CLI and it did work, but the restore command still segfaulted. I will add logs at the end of the post.

Here are the logs-
