Dear Mac Experts,
After upgrading to Version 10.0.5.47871 just 2 minutes ago, when I hit Play on Bnet, it gives me the below error,
World of Warcraft
The CAS System was unable to initialize:
Unable to initialize CAS from build info
file. No active install info entries.
Tact instance creation failed. Error (1): unknown failure
There is no error file in the Errors folder.
Yesterday before this update I was able to play it fine but today after updating to Version 10.0.5.47871 I can’t even launch the game. 
Below is my Mac Spec:
Mac Mini 2018
CPU: Intel i5
RAM: 64 GB
Storage: 256 GB
OS: Ventura 13.2 (the latest version)
Note: I am running World of Warcraft from an 128-GB USB. It has been running and launching the game fine before this launch issue after the WoW version update on Bnet.
Please advise. Thanks!
