When I try to download new packages, or update anything, I get a Segmentation fault (core dumped) error. Initially, it appeared after I used grub customizer and tried to swap the windows and ubuntu boot menus. After that, the program closed and did not open again. I tried reinstalling it, it didn't help. After this failure, I try to reinstall grub using boot-repair, but it also does not help.
sudo apt install --reinstall grub-efi-amd64
