I can't login because of this error.

Do you have the game installed on the C drive (same drive as your OS) if you don't, I would completely uninstall and reinstall on the C drive.
Usually those DX errors pop up after certain game files get corrupted, usually related to the drive the game is installed on not being C, but a secondary or external drive being used.

You can try installing the game in the Program Files folder (if the x86 version folder still gives this error), or install the game directly on to the C drive "This PC > Windows > Here" for example.
If you still get the errors, I would test by installing on a different drive, even an external drive and see if it makes any difference at all.

unfortunately i can't install it on c:. it was always on an external drive, so idk what changed. at this point, the game takes up too much space and my ssd don't have a lot of it
i'm gonna try another drive though, i'll update if it works. thank you!!! xox

PS : Installing the game on a separated hdd seems to be working. Logged in a few times and haven't gotten that error yet. Not on (C with OS, or (D with the usual storage stuff. Although, can't confirm or deny that'll work on (C because i don't have that much space left to try it.

Thank you all for the help!
