Unable to connect to debugger: "Waiting for program to start"

[kire256]

Hello. I had been able to use the debugger when connecting to the emulator until just recently. Now, when I start debugging, the message "waiting for program to start" appears. I checked the log, and it includes this error:

Error - monitor_open: could not open monitor console. Sound: Opened device dx', speed 48000Hz, fragment size 2.67ms, buffer size 32.00ms
reSID: MOS8580, filter on, sampling rate 48000Hz - resampling, pass to 21600Hz
Sync reset
Unit 8: RESET.
Increasing trap_func array size to 1 with 1 to run
Error - vice_network_send: internal error
Error - vice_network_send: internal error
Error - vice_network_send: internal error`

I'm not sure where to go from here. Any suggestions on solving this would be appreciated. I can still run the game in the emulator, but the debugger no longer attaches.

I'm using version 3.8 of the Vice emulator if that helps. I did notice that there was a similar discussion, but the cause doesn't seem to be the same AFAICT.
