Expected / Desired Behavior / Question

The SPFx project builds successfully after installing @pnp/spfx-property-controls

Observed Behavior

The build fails immediately after this dependency is installed until the dependency is deleted and the entry is removed from config.json localized resources. The error messages are as follows:

[17:31:49] Finished subtask 'configure-webpack' after 1.18 s
[17:31:49] Starting subtask 'webpack'...
[17:31:49] Error - [webpack] Error processing webpack stats: TypeError: Cannot read property 'toJson' of undefined
[17:31:49] Error - [webpack] Webpack error: TypeError: Cannot set property 'asyncChunks' of undefined

Steps to Reproduce

Run npm install @pnp/spfx-property-controls --save --save-exact in an adaptive card extension project using SPFx v1.18
run gulp serve
observe webpack error output

I'm getting this error not when I install the dependency, but when I attempt to use it. I'm trying to build a custom webpart with a PropertyFieldPeoplePicker.
