seeing the same issue here (ASIO driver installed and rebooted).

the debugger tells me:

```auto
The debugged process stopped because it triggered an exception.

Stopped in thread 0 by: Exception at 0x1400b41a3, code: 0xc0000005: read access violation at: 0x0, flags=0x0 (first chance).

```

… which somewhat implies a nullptr dereference …
