Good practice wants that asynchronous code should not block the activation of the plugin as it may delay the full application start up.

A better pattern is therefore to use a Promise approach:

Suggested change
let settings: ISettingRegistry.ISettings;
try {
settings = await settingRegistry.load(variableinspector.id);
} catch (error) {
console.error('Failed to load settings for the Git Extension', error);
}
Promise.all([settingRegistry.load(variableinspector.id), app.restored])
.then(settings => {
// ... here use the settings
})
.catch(error => {
console.error('Failed to load settings for the Git Extension', error);
});


/**
* Create and track a new inspector.
*/
function newPanel(): VariableInspectorPanel {
const panel = new VariableInspectorPanel();
const panel = new VariableInspectorPanel(settings);

This is not the best approach as it add an opinionated interface on how the filter state is stored. To ease code maintenance, extensibility and testing, the best is to not passed the settings object but rather to add filter setters on the panel.

Now the trouble raises from how to pass information from the settings only available within the promise to the panel.

The best solution would be to refactor substantially the code as it is a bad idea to embed the view panel in the manager.

But let's go for a simpler fix for now. You could use a PromiseDelegate like this:

const settings = new PromiseDelegate<ISettingRegistry.ISettings>();

Promise.all([settingRegistry.load(variableinspector.id), app.restored])
.then(settings_ => {
  settings.resolve(settings_);
})
.catch(error => {
  console.error('Failed to load settings for the Git Extension', error);
  settings.reject(error);
});

Then change the command execute to be async:

      execute: async () => {
        if (!manager.panel || manager.panel.isDisposed) {
          await settings; // Wait for the settings to be loaded
          manager.panel = newPanel();
          // Best would be to use a single array of filter object: {filter: '', type: ''}[]
          // to clarify the binding between the type and the filter
          manager.panel.filters = settings.filters;
        }
        if (!manager.panel.isAttached) {
          labShell.add(manager.panel, 'main');
        }
        if (manager.source) {
          manager.source.performInspection();
        }
        labShell.activateById(manager.panel.id);
      }


panel.id = 'jp-variableinspector';
panel.title.label = 'Variable Inspector';
