I believe the main issue here is that you are using a technology preview version of the browser which is ahead of the official one. I also believe the team is aware of the changes and will keep up the framework with the changes when all the browsers will adopt the current webgpu change of getting the adapter info.
You can make changes in the current version of webgpuEngine.ts line 643 and compile the framework:
if ((this._adapter as any).info) {
this._adapterInfo = (this._adapter as any).info;
} else {
this._adapter.requestAdapterInfo().then((adapterInfo) => {
this._adapterInfo = adapterInfo;
});
}
