Hi,  
I downloaded the add-on image occlusion and add it on my anki but when I click on it to use it on my cards it says that an error happened. What can I do ?

Debugging information :

Anki 2.1.54 (b6a7760c) Python 3.9.7 Qt 5.15.2 PyQt 5.15.5  
Platform: Windows 10  
Flags: frz=True ao=True sv=2  
Add-ons, last update check: 2022-08-30 09:34:22

Caught exception:  
Traceback (most recent call last):  
File “anki.config”, line 43, in get\_immutable  
File “anki.\_backend.generated”, line 1004, in get\_config\_json  
File “anki.\_backend”, line 146, in \_run\_command  
anki.errors.NotFoundError

The above exception was the direct cause of the following exception:
