Unabe to login ZWIFT

I apologize in advance that English is not my first language.

Since Jul’ 22, I haven’t able to login ZWIFT. (An unexpected error has occurred)
I reinstalled ZWIFT and reboot my PC,but can’t be fixed.
There are some Err MSG in my local log file,
"ASSERT: ““Streamer: ERROR: ImportStreamingFilesDB() - Loading streaming files db!” && bLoadedOK”, file=D:\Projects\ZwiftApp\CODE\Streamer.cpp, line=466 ”
It would be helpful if you could tell me how to repair this state.
