Exception window on launch and then non-functional

[hwfwalton]

I'm on Windows 10. I tried both the installed version and the portable version just in case.

I get a Windows exception alert window as soon as I try to launch WAT.exe and the app remains non-functional even if I choose "Continue". The exception reappears every few minutes if I leave the WAT app open.

Based on a cursory peak at the stack trace, it seems like it might just be an issue with parsing the JSON response from a Warframe worldstate API. The behavior of the exception reappearing every few minutes would align with that (reappearing due to the app re-requesting the world state).

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:

<configuration>
    <system.windows.forms jitDebugging="true" />
</configuration>

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.

Probably. Not sure if you noticed, but the app was created more than 3 years ago, so the probability that the format moved on since that time is incredibly high.
