The error occurs occasionally when loading multiple houses simultaneously

Hi, I'm trying to load the multiple procthor-10k houses simultaneously， sometimes, the code works, but sometimes I get the following error :

```
Process ForkServerProcess-1:

token = next(token for token in tokens.split("\n") if token.endswith("github.com"))
StopIteration
```

Can you help me to solve this problem?
Thanks,
