Arch with lightDM and cinnamon won't start after updating

I updated my Arch system for the first time in about a moth today. To make sure everything was refreshed and all that, I restarted my computer after the update had finished. GRUB started up normally and showed me the Arch linux with linux linux option and all that. All of the stuff before the graphical stuff started up normally, showing me the startup messages about journals and shit. As is the norm, when graphics started up, my screen turned purple and then shut off. Normally, after that it will start back up, be purple for a second and lightDM will start. Instead, it went to a black screen with green pixels all over it and turned off again. Then it turned back on with pink screen with large white pixels all over it, turned off, and came back with the pink pixel screen. I tried hitting ctrl+alt+f1-12, but I couldn't get into any ttys. It just won't start! I tried looking on the internet and these forums to see if anyone else had these issues, but I couldn't find any info. Could someone help me figure this out?

Re: Arch with lightDM and cinnamon won't start after updating

I managed to get into my system without any graphics. I tried "sudo xinit cinnamon-launcher" and i got this message:

Failed to connect to session bus: Error spawning command line dbus-launch --autolaunch=da9998a61183c4c50b1664fd8455a2565 --binary-syntax --close-stderr: Child process exited with code 1Traceback (most recent call last):
   File "/usr/bin/cinnamon-launcher", line 72, in <module>
      os.execvp(FALLBACK_COMMAND, (FALLBACK_COMMAND,) + FALLBACK_ARGS)
   File "/usr/lib/python3.9/os.py", line 574, in execvp
      _execvpe(file, args)
   File "usr/lib/python3.9.os.py", line 616, in _execvpe

   File "/usr/lib/python3.9/os.py", line 607, in _execvpe
      exec_func(fullname, *argrest)
FileNotFoundError: [Errno 2] No such file or directory

I'm not 100% sure what that means. At first I thought it meant I didn't have /usr/lib/python3.9/os.py, but I do have that file, so maybe it corrupted? Maybe these are standard errors and something else is wrong?
HOWEVER, doing "sudo xinit cinnamon-session" doesn't cause any issues and it just starts up cinnamon normally, albeit without any of my customizations. If this info is useful, please let me know, even if you can't help.
