Second Monitor suddenly not working

Hey all! I'm having an issue with my second monitor. I do not know what caused this, but while I was working on a project on my computer, my second monitor suddenly blanked. It no longer shows up in the display settings, however, it works perfectly fine when using Windows, booting, and on the login screen (the screen isn't even mirrored, it's registered as a second display entirely.)
Reverting to a previous snapshot fixes this, but I can't do this because I have important progress made with my project on my current snapshot that would be reverted by going to a previous one.
I have a Ryzen 7 2700X and an R5 570 if this information helps.
If anyone has any ideas as to what the issue could be, please let me know, and thank you in advance!

Snapshots only restore / (in the default setting).

It maybe worth looking at the last pacman log to see which update may be breaking your system

s a i n t

logs told me this:

[2022-01-24T17:23:16-0600] [ALPM-SCRIPTLET] >>> This driver now uses DRI3 as the default Direct Rendering
[2022-01-24T17:23:16-0600] [ALPM-SCRIPTLET]     Infrastructure. You can try falling back to DRI2 if you run
[2022-01-24T17:23:16-0600] [ALPM-SCRIPTLET]     into trouble. To do so, save a file with the following 
[2022-01-24T17:23:16-0600] [ALPM-SCRIPTLET]     content as /etc/X11/xorg.conf.d/20-intel.conf :
[2022-01-24T17:23:16-0600] [ALPM-SCRIPTLET]       Section "Device"
[2022-01-24T17:23:16-0600] [ALPM-SCRIPTLET]         Identifier  "Intel Graphics"

[2022-01-24T17:23:16-0600] [ALPM-SCRIPTLET]       EndSection

creating a 20-intel.conf file (even though i have an... amd... card..... also i didnt have to put anything in there at all) suddenly revived my second monitor. It probably shouldve been my first instinct to check logs haha

thank you to the both of you!
