Kernel panic following GLIBC upgrade

I was trying to install software on Deepin Linux 20 that required an higher version of GLIBC. I found a Stack Overflow question about how to do that and followed the instructions on some of the answers. Now whenever I try to boot the computer, the Deepin logo shows and freezes (it is supposed to be animated). The computer does not respond to any keystrokes, including the one to hide the logo and show the text output. How do I check boot logs or undo this change if I can't even boot to a terminal? I can boot to another system, but am not sure how I can repair the main one offline. After following a suggestion in the comments to remove quiet and splash from the boot options, I now have details about the issue. Towards the bottom, I have the line:

---[ end Kernel panic - not syncing: Attempted to kill init! exitcode=0x0007f00 ]---

I also have a line that I believe is causing the kernel panic:

/init: line 83: wait-for-root: not found

Another line that details the kernel panic:

/sbin/init: error while loading shared libraries: libcrypt.so.1: cannot open shared object file: No such file or directory
