Crash when adding token in 5.2

Cesium for Unreal
1

With a brand new project, I add the Cesium plugin and restart. When I add my token and click the ‘Create New Project Default Token’, I get this error. I have done this half a dozen times before without issue, but never in 5.2 with the latest plugin.

Unhandled Exception: EXCEPTION_ACCESS_VIOLATION reading address 0xffffffffffffffff

I wrote up an issue for this:

You should be able to work around it by clicking on the words “Specify a token”. That will change the label on the button, and clicking it will no longer crash.

Thanks. I didn’t realize I wasn’t logged in. Once I read your message I realized I needed to scroll down and login. Once I did everything worked fine!
