PLEASE HELP - A JavaScript Error Occurred in the Main Process

My Discord was working, one day I open Discord and randomly get this error, I have done a clean uninstall MANY time and when I try to install Discord again I get the error message. I have Googled it many times and I cannot find the specific error I have. I can send screenshots or post them or whatever.

The first line is - Uncaught exception: Error: 1% is not a valid Win32 application.

I am aware it may be a virus or malware, I downloaded that WinThruster thing and it said it found 150-something errors and I did my 25 free ones but I still have 129 according to that. I did a Windows Defender scan and it says 18,444 files scanned with no threats found. I'm lost, would it be worth paying for that WinThruster thing? I REALLY love Discord and all of my friends, as well as me have uninstalled Teamspeak and haven't used Skype in two years and aren't willing to go back to either of those.
