Re: "Unable to Load Persistence Data" - Season 2 / Season 3

I have been suffering from the identical symptoms ever since I bought this game on its release date.
In addition to the error code in the title, I sometimes get error code: 15:600P:-7A under the same conditions.
I'll post a screenshot of the symptom when it occurs (this is what is displayed in my native language, but the exact same text is displayed except where the error code is).
Like the founder of this topic, I can play other games and after connecting to the main menu (with luck...or by pressing "OK" for more than an hour and patiently retrying to load), the game experience is completely unaffected. The game experience is not affected in any way.
The connection speed is consistently over 150 mbps, so we do not expect any problems with the connection environment in the future.
Here are some other data about my playing environment. Please share your wisdom to help me solve this problem.

PC(Steam)
CPU: Intel Core i7-6700k (4.0GHz)
GPU: NVIDIA Geforce 2070SUPER 8GB
RAM: DDR4-16GB
