When I'm enumerating I get the following error:

Process lookup-21:
Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/dns/resolver.py", line 1106, in nameservers
    raise NotImplementedError
NotImplementedError

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "/usr/lib/python3.11/multiprocessing/process.py", line 314, in _bootstrap
    self.run()
  File "/home/pegasus/Documents/Sublist3r/subbrute/subbrute.py", line 334, in run

The script runs for a while. But after some time, it throws the above error. My python version is 3.11.4

The command I'm using: python3 sublist3r.py -v -b -d <domain_name> -t 50

The issue is resolved. I was running curl command at the same time on another terminal. Running standalone sublist3r worked fine.
