[BUG] odrive preferences screen is blank

[mcamou]

Describe the bug

When I open the odrive Preferences screen, it is completely blank. If I start odrive from the command line I get the following errors over and over again:

{ Error: Cannot create a string longer than 0x3fffffe7 characters
    at stringSlice (buffer.js:595:43)
    at Buffer.toString (buffer.js:668:10)
    at FSReqWrap.readFileAfterClose [as oncomplete] (internal/fs/read_file_context.js:48:23) code: 'ERR_STRING_TOO_LONG' }

As an additional data point, I just changed my Google password which invalidated all tokens.

To Reproduce
Steps to reproduce the behavior:

1. Run odrive from the command line
2. See the error
3. Right click on the ODrive icon in the system tray
4. Click on 'Preferences...'
5. The Preferences window is blank

Expected behavior

The Preferences screen should appear. If the issue is related to an invalid token, it should ask me to reauthenticate.

Desktop (please complete the following information):
