Unable to add SHP from GEE Assets into QGIS via QGIS-GEE plugin

This might come across as a duplicate question here but I cannot find a way out.
I’ve got two shapefiles uploaded in Assets in GEE against my username.
I am trying to add them into QGIS and it fails all the time.

I can confirm that the GEE plugin has been installed correctly because I can load imagery without any issues. Also, I am able to perform analysis in GEE but want to do so in QGIS because there are certain things that are a bit easier there.

The code I’m trying is as follows:

poly_layer = ee.FeatureCollection('users/myusername/folder/polygon');
Map.centerObject(poly_layer);

The error I’m getting is as follows:

Traceback (most recent call last):   File "C:UsersmynameAppDataRoamingQGISQGIS3profilesdefaultpythonpluginsee_pluginextlibs_windowseedata.py", line 338, in _execute_cloud_call

During handling of the above exception, another exception occurred:
