Rack browser crash

[Gavin Rough]

Hi there - I've tried creating an empty widget just to try and get started with SvgHelper since it seems like a helpful tool. My widget code looks like this:

struct MyModuleWidget : ModuleWidget, SvgHelper<MyModuleWidget> {
  MyModuleWidget(MyModule *module) : SvgHelper<MyModuleWidget>(*this) {
    setModule(module);
    loadPanel(asset::plugin(pluginInstance, "res/MyModule.svg"));
  }
};

This seems to crash Rack somewhere near the createPreview() function of the module browser.

[5.375 info src/app/Browser.cpp:201 createPreview] Creating module widget MyPlugin MyModule

I'm wondering if this is a familiar problem and if there might be a way around it. This is on VCV Rack 2.3.0 macOS x64. Thanks
