Repeatable JavaScript error when trying to save preferences

Two days ago, I opened DW18CC and my window was back to the white default view. I went into prefs to change it and every time I clicked "apply", It would get 3 pop ups saying "While executing onLoad in writePreference.htm, a JavaScript error occurred." I cannot change any of my preferences without the errors.

I checked the log at C:\Users\[XXXX]\AppData\Roaming\Adobe\Dreamweaver CC 2018\en_US\Configuration\Logs and saw (yes, the log has spelling errors):

JS Error:

Folder is not defined

filename: ignore

lineno: 127

JS Error:

Could not exceute script

JS Error:

logFile.open is not a function

filename: ignore

lineno: 227

JS Error:

Could not exceute script

While executing onLoad in writePreference.htm, a JavaScript error occurred.

While executing onLoad in writePreference.htm, a JavaScript error occurred.

I have tried deleting my caches, cloud sync folder, my workspaces, and followed the "troubleshooting JavaScript errors" page on Adobe's site. Nothing seems to help.
