device descriptor request failed

[deskat-dan]

When I build the project using the discovery configuration (without changing the config file), I get a "device descriptor request failed" error after flashing and connecting to the PC. But if I flash a pre-built firmware, everything works perfectly.
Build log below:

The problem is fixed—you need to exit the venv to build. BUT in the latest version (7.11.1), building throws an error (link), while older versions compile without issues.
