Not sure this is the right place to post this but here goes.
In My Accounts tab, I noticed that the side-bar was not going all the way down when using mouse scroll. So I used the mouse and dragged it all the way down. That's when the error popped up.
Here're the details:
Code:
See the end of this message for details on invoking
just-in-time (JIT) debugging instead of this dialog box.

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.
When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.
Yeah it's a known problem, unfortunately as it stands it can't be fixed in this version so you will just have to avoid using the mouse until the new launcher is completed.
