I previously used the Google Sync Plugin. Added this plugin because of a change to Google Authentication.
After installation, I first wanted to configure the plugin but receive a null reference exception error every time I attempt to.

To Reproduce
Steps to reproduce the behavior:

1. Install Plugin in \Plugins\KPSyncForDrive
2. Open existing KeePass2 db
3. Click on Tools -> KP Sync for Google Drive -> Configure
4. See error

Expected behavior
Should open the configuration window as described on this KP Sync page.

Screenshots

Please complete the following information:

• OS: Windows 10 1909 Build 18363.1500
• KeePass2 2.47 (Portable)
• KPSync for Google Drive 4.0.6
• Other Plugins Installed
• KeeAgent 0.12.1

Additional context

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.

For example:

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.
