Wwise Launcher won't open and, when reinstalled, same problem occurs.

Question

Hi,

My PC crashed when working on a Wwise project which was integrated with a Unity project. When I went to re-open the Wwise Launcher after the crash - I got the error message:

"An error occurred. We are sorry for the inconvenience. If you were in the middle of an installation, please restart the wwise launcher and try again. Details: Syntax Error: Unexpected token"

I have no idea what to do, as I can't open Wwise, I've tried multiple different ways to try and 'force' open it, but to no avail, and having uninstalled and reinstalled various times, the problem persists, so I physically can't open Wwise which is really frustrating. 

I am running Windows 10 pro Version 20H2 on 64 bit OS

I am new to the forums so if you need any more info then please let me know and I'll be happy to provide.

I desperately hope someone can help!

Thanks in advance
